Determine the molar mass of a 0.314-gram sample of gas having a volume of 1.6 L at 287 K and 0.92 atm. Show your work.

The molar mass of the sample of gas is 5.020 grams per mole.

Explanation:

Let suppose that the gas sample behaves ideally, its equation of state will be:

(1)

Where:

- Pressure, in atmospheres.

- Volume, in liters.

- Mass, in grams.

- Molar mass, in grams per mole.

- Temperature, in Kelvin.

- Ideal gas constant, measured in atmosphere-liters per mol-Kelvin.

If we know that , , , and , then the molar mass of the sample is:

The molar mass of the sample of gas is 5.020 grams per mole.

it is stable as it is in group 0 which have full outer shells of electrons
