In the laboratory, the temperature is 295 k and the total pressure in the gas-collecting tube is 748. 6 mmhg. If the vapor pressure of water at 295 k is 19. 8 mmhg, determine the pressure of the h2(g) in the gas-collecting tube.

Answers

Answer 1

According to the Dalton Law in a blend of non-reacting gases, the entire pressure will be equivalent to the total of partial pressures of the individual gases.

The pressure of H₂ gas collected in the tube will be 728.8mm Hg.

This can be calculated by:

Dalton's formula:

Ptotoal = PH2O + PH2

Given :  

Ptotal = total pressure of gases = 748. 6mm Hg

PH2O = partial pressure of water = 19.8 mm Hg

PH2 = partial pressure of hydrogen = ?

Now using the formula we will calculate:

748. 6mm Hg = 19.8 mm Hg + PH2

728.8mm Hg =  PH2

Therefore, the pressure of the hydrogen in the tube is 728.8mm Hg.

Hence  728.8mm Hg is a correct answer.

would you need to use molar mass in this question? how many moles are in 4.5 x 10^24 particles of water?

Answers

7.471 moles are present in 4.5 x 10^24 particles of water.

What is the mole?

The mole, which is denoted by the symbol "mol," is the volume of a system that includes as many elementary particles as there are atoms in 0.012 kilograms of carbon 12.

We have a clear idea of how many molecules makeup 1 mole of any given substance according to Avogadro's hypothesis. This implies that 6.02x1023 molecules are also present in 1 mole of water.

Now, assuming a mole of water has 6.02x10^23 molecules in it.

As a result, X mol of H2O will contain  4.5 x 10^24 molecules, or

X mol of water = (4.5 x 10^24)/6.02x1023 or 7.471 moles of water.

what is the molar mass of a substance if a total charge of 4934.5 c deposited 5.47 g of the substance on an electrode through a reaction involving 2 electrons?

Answers

To find the molar mass of a substance from the given information, you need to first determine the number of moles of the substance that was deposited on the electrode.

The charge on an electron is about -1.60 x 10^-19 coulombs, so the total charge of 4934.5 c deposited on the electrode corresponds to about 3092.19 moles of electrons. Since the reaction involves two electrons per mole of the substance, the number of moles of the substance deposited on the electrode is about 1546.1.

The molar mass of a substance is the mass of one mole of the substance, so to find the molar mass of the substance in this case, you need to divide the mass of the substance deposited on the electrode (5.47 g) by the number of moles of the substance (1546.1):

Molar mass = (5.47 g) / (1546.1 mol) = about 0.00356 g/mol

The unit for molar mass is usually grams per mole (g/mol), so the molar mass of the substance in this case is about 0.00356 g/mol.
