Determine the molar mass of each of the following gases:

a) 0.92 g of a gas that occupies 470 mL at 0 ∘C and 1.00 atm (STP). Express your answer to two significant figures and include the appropriate units.

b) 1.39 g of a gas that occupies 1.45 L at 0 ∘C and 760 mmHg (STP). Express your answer to three significant figures and include the appropriate units.

c) 1.33 g of a gas that occupies 1.50 L at 675 mmHg and 18.0 ∘C. Express your answer to three significant figures and include the appropriate units.

d) 3.0 g of a gas that occupies 2.5 L at 0.93 atm and 17 ∘C. Express your answer to two significant figures and include the appropriate units. The units ARE NOT gmol^-1

Answer #1

The mass of gases is given in the grams unit. And from the given data we can calculate moles of gas to step ahead for molar mass. So the molar mass should be in gram/mol unit.

If any query regarding this please comment here. Thank you :)
