Strategy Plan STEP 1: What unit is asked for in the answer? STEP 2: What given value is related to the answer? STEP 3: What unit factor(s) should we apply? From the molar volume of a gas at STP, 1 mol = 22.4 L; thus, the unit factors are 1 mol/22.4 L, and 22.4 L/1 mol. Unit Analysis Map given value 17.04 g 1 mol X unit factor 1 mol 22.4 L Step 1: Step 2: Step 3: unit in answer g = 1 mol 22.4 L L g/L 17.04 g/mol or 22.4 L 1 mol
