What is the molar mass of a gas with a density of 3.50 g/L at a
temperature of 345 K and a pressure of 0.950 atm? (Write your
answer whole number e. g. 345)
g/mol

Explanation:

Use the ideal gas equation:

Where:

Use the molar mass of the gas to include the density in the formula:

Clear n/V from the gas ideal equation and subsittute with density/molar mass:

Now you can subsitute the data:

molar mass = (3.50g/liter) × 0.08206 atm.liter/(K.mol) × 345K / 0.950 atm
