Question

A gas has a density of 1.43 g/l at a temperature of 27°c and a pressure of 0.779 atm. Calculate the molar mass of the gas.

Answer 1

The molar mass of the gas is 28.11 g/mol.

Step-by-step explanation:

To calculate the molar mass of a gas, we can use the ideal gas law formula:

density = (molar mass * pressure) / (molar volume * temperature)

Rearranging the formula, we have:

molar mass = (density * molar volume * temperature) / pressure

Using the given values:

molar mass = (1.43 g/l * 22.4 L * (27 + 273) K) / 0.779 atm

Simplifying the equation:

molar mass = 28.11 g/mol
