A sample of hydrogen gas, H₂, has a volume of 5.86 L at a temperature of 273K and a pressure of 1.5 atm. Calculate the number of moles of H₂ present in this gas sample. Assume that gas behaves ideally.
a
5.86 mol
b
0.57 mol
c
0 mol
d
0.39 mol



Answer :

The option (d) will be correct, that is the answer would be 0.39 mol.

Ideal gas equation is also known by the  name of the general gas equation.

It is already mentioned in the problem,

Volume , V = 5.86 L

Temperature , T = 273 K

Pressure, P = 1.5 atm

Ideal Gas Equation : PV = nRT

n = PV / RT

= 1.5  atm * 5.86 L / 0.0821 L atm mol^-1 K^-1 * 273 K

=  8.79 / 22.41 mol

=0.39 mol

Hence the number of moles of H2 found in the gas sample is 0.39 mol.
