How many grams of Neon are there in a 346 mL container at 40.5°C and 842 torr?

With steps!

Answers

Answer 1

Answer:

Mass of neon = 0.3 gram

Explanation:

Given:

Pressure = 842 torr

Temperature = 40.5°C = 313.5 K

Volume = 356 ml = 0.346 l

Find:

Mass of neon

Computation:

Gas constant R = 62.363

Number of mole = (842)(0.346)/(62.636)(313.5)

Number of mole = 0.015 (Approx)

Molar mass of neon is 20 g/ml

So,

Mass of neon = 20 x 0.015

Mass of neon = 0.3 gram

How many CO2 molecules in 0.0189 mol of CO2?

.11 x 1022 molecules

.624 x 1023 molecules

1.14 x 1022 molecules

Answers

Answer:

option C is correct = 1.14 × 10²² molecules of  CO₂

Explanation:

Given data:

Number of moles of CO₂ = 0.0189 mol

Number of molecules = ?

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

For example,

18 g of water = 1 mole = 6.022 × 10²³ molecules of water

For given question:

1 mole of CO₂ =  6.022 × 10²³ molecules of  CO₂

0.0189 mol of CO₂ ×  6.022 × 10²³ molecules of  CO₂ / 1mol

1.14 × 10²² molecules of  CO₂

Thus, option C is correct.

URGENT HELP!!!! IN NEED OF EXPERT ANSWERS!!!PLEASE!!!!! WILL MARK BRAINLIEST!!!!!!!!!!!!!!!!!!!!!!!!! My question is.... Would you consider the triple point of cyclohexane to be a chemical or physical property? Why?

Please watch a video on "Triple point of Cyclohexane." before responding

Answers

Answer:

Physical property

Explanation:

Physical properties differ from chemical properties in that a different substance is formed during a chemical process whereas, a physical property produces NO 'new' substance upon completion of change.  By definition, 'Triple Point' is the temperature-vapor pressure value where the substance of interest exists in all three states simultaneously; that is, solid, liquid and gas. In this, the chemistry of cyclohexane remains unchanged regardless of temperature-pressure conditions and no new compounds are formed as products of change.

Example:

At the triple point of cyclohexane C₆H₁₂(s)  ⇄  C₆H₁₂(l) ⇄ C₆H₁₂(g) ⇄ C₆H₁₂(s),  the cyclohexane is still cyclohexane regardless of state and is classified as a physical process. The combustion of cyclohexane in the presence of oxygen, however, produces new substances  (CO₂(g) and H₂O(g)) having chemical and physical properties different from original cyclohexane added in the process.

For the combustion of C₆H₁₂(g) => 2C₆H₁₂(g) + 13O₂(g) => 12CO₂(g) + 2H₂O(g) produces substances (CO₂(g) and H₂O(g)) having different physical and chemical properties than the C₆H₁₂(g) introduced into the system and is classified a chemical process.

If a 5.00% citric acid solution contains 5.00 grams of citric acid in every 100.0 mL of the solution, how many grams of citric acid are present in 375 mL of the 5.00% (w/v) solution? show your work using dimensional analysis and report your answer with the correct number of significant figures

Answers

Answer:

18.8 g Citric acid

Explanation:

We have a 5.00% (w/v) citric acid solution, that is, there are 5.00 grams of citric acid every 100.0 mL of the solution. We can use dimensional analysis to calculate the grams of citric acid in 375 mL of the 5.00% (w/v) solution.

375 mL Solution × (5.00 g Citric acid/100.0 mL Solution) = 18.8 g Citric acid

What type of attachment is displayed when a child actively explores the environment but seeks out the caregiver for reassurance or comfort?

I didnt see an answer for this so I thought Id answer it myself. The answer is C secure. (Edge 2020) Hope this helps!

Answers

Answer:

C - Secure

Explanation:

Edg 2020

Anxious-Ambivalent attachment is displayed when a child actively explores the environment but seeks out the caregiver for comfort or reassurance.  

• The form of attachment when children seem to distrust caregivers, and this insecurity usually signifies that their surroundings is explored with trepidation rather than excitement is known as Anxious-Ambivalent attachment.  

• In this form of attachment, children continuously look for approval from their caregivers and spontaneously observe their environments for fear of being abandoned.  

• The children developing under this form of attachment style, seem to carry what they have acquired into adulthood, and usually feel unloved by their partners.  

Thus, the given case is of Anxious-Ambivalent attachment.

Answer:

2.29 moles of SF₆ contain 334.5 g SF₆

Explanation:

Given data:

Mass of SF₆ = ?

Number of moles of SF₆ = 2.29 mol

Solution:

Formula:

Mass = number of moles × molar mass

Molar mass of SF₆ = 32.065 + (19)×6

Molar mass of SF₆ = 146.06 g/mol

Now we will put the values in formula.

Mass = 2.29 mol ×  146.06 g/mol

Mass = 334.5 g

2.29 moles of SF₆ contain 334.5 g SF₆ .

An unknown compound contains only C , H , and O . Combustion of 5.60 g of this compound produced 13.7 g CO2 and 5.60 g H2O . What is the empirical formula of the unknown compound?

Answers

Answer:

Empirical formula of compound  is C₄H₈O

Explanation:

Given data:

Mass of compound = 5.60 g

Mass of CO₂ = 13.7 g

Mass of H₂O = 5.60 g

Empirical formula of compound = ?

Solution:

Percentage of C:

13.7 g/5.60 g × 12/44× 100

2.45×0.273× 100 = 66.9%

Percentage of H:

5.60 g/ 5.60 g × 2.016/18 × 100

11.2%

Percentage of O:

(66.9% + 11.2%) - 100 = 21.9%

Grams atom of  C , H, O

66.9/12 = 5.6

11.2 / 1.008 = 11.11

21.9 / 16 = 1.4

Atomic ratio:

           C                 :               H           :              O

           5.6/1.4         :            11.11/1.4    :            1.4/1.4

What is the density of an unknown metal in g/mL if a sample of the metal has a volume of 520 mL and a mass of 2344 g?

Answers

Answer:

The correct answer is 4.5 g/mL.

Explanation:

To find the density, we must remember the formula for density, which is given by the following:

density = mass/volume

In this case, we are given both the mass and the volume, so we just need to plug in these values into the formula to solve for the density.  This is modeled below:

density = mass/volume

density = 2344 g/520 mL

density = 4.5 g/mL

Therefore, the correct answer is 4.5 g/mL (notice that the units for our answer match what is being asked for in the problem).
