Below are sample questions representative of the exercises included on this worksheet and related 11.54 Ideal Gas Law and Molar Volume skill assessments:

Problem 1Difficulty: Mastery

A chemistry simulation shows PV/RT = 0.250 for a gas sample. What is the best interpretation of this value?

AThe sample has a molar mass of 0.250 g/mol.

BThe sample occupies 0.250 L at all conditions.

CThe sample temperature is 0.250 K.

DThe sample contains 0.250 mol of gas.

Solution & Explanation:Rearranging PV = nRT gives n = PV/RT, so the value 0.250 represents moles of gas.

Problem 2Difficulty: Mastery

Which student statement is most accurate about molar volume?

AAt the same temperature and pressure, heavier gases always occupy larger volumes.

BAt STP, 1 mol of every ideal gas occupies 1.00 L.

CAt the same temperature and pressure, equal moles of ideal gases occupy equal volumes.

DMolar volume depends only on molar mass.

Solution & Explanation:Ideal-gas volume depends on n, T, and P. At equal T and P, equal moles occupy equal volumes regardless of identity.

Problem 3Difficulty: Mastery

A lab report lists P = 101.2 kPa, V = 0.445 L, T = 295 K, and mass = 0.800 g for a dry gas. What molar mass should be reported? Use R = 8.314 L kPa/(mol K).

A21.8 g/mol

B43.6 g/mol

C87.1 g/mol

D0.800 g/mol

Solution & Explanation:Find n = PV/RT, then M = mass/n. The calculation gives M = 43.6 g/mol.
