The density of a gas in 1.79grams per liter at STP. What is the molecular mass of the gas

we have 1.79g of gas per liter of gas

there are 22.4 liters of gas in 1 mole at STP so we have 1(L) / 22.4 (L/ mole) of gas in a liter
= 0.04464 moles

so in 1 liter 0.04464 moles has mass of 1.79g

1 mole has mass of 1.79 / 0.04464 = 40.01 g / mole ,, molar mass
