Question

A 0. 50 l sample of a gas has a mass of 11. 3 g at stp. what is the mass of 1. 00 mol of this gas? in other words, what is the molar mass (molecular weight)?

Answer 1

the molar mass of the given sample is 44.24kg.

To find the answer, we have to know about the concept of mole.

How to find the molar mass of the sample?

• Mole is the amount of substance that containing Avogadro number of particles.
• We can write the expression for mole as,

                      $mole,n=\frac{m}{M}$

where, m is the given mass and M is the molar mass.

• Given that, the 0.5 mol of sample has a mass of 11.3g. Thus the molar mass will be,

                      $n=\frac{m}{M} \\M=\frac{n}{m}=\frac{0.5}{11.3*10^{-3}} =44.24kg$

• The mass of 1 mole of given sample will be,

                       $m=n*M=1*44.24kg=44.24kg$

Thus, we can conclude that, the molar mass of the given sample is 44.24kg.
