A 1300 mL sample of gas with a molar mass of 71.0 g/mol at STP has what density?

0.055g/mL

Explanation:

Data obtained from the question include:

Molar Mass of the gass sample = 71g/mol

Volume of the gas sample = 1300 mL

Density = ?

The density of a substance is simply mass per unit volume. It is represented mathematically as:

Density = Mass / volume.

With the above equation, we can easily obtain the density of sample of gas as illustrated below:

Density = 71g / 1300 mL

Density = 0.055g/mL

Therefore, the density of the gas sample is 0.055g/mL
