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 O3 = 22.4 LO3. The molar mass from the periodic table is 48.00 g 03 1 mol O3. Thus, the two pairs of unit factors are shown in Step 3. Unit Analysis Map given value 3.36 L 03 X unit factor 1 1 mol 03 22.4 L 03 Step 1: Step 2: Step 3: X 1 mol 03 22.4 L 03 1 mol 03 48.00 g 03 g 03 3.36 L 03 unit factor 2 48.00 g 03 1 mol O3 or or 22.4 L 03 1 mol 03 48.00 g 03 1 mol O3 unit in answer ? g 03 =
