Solution
How many H2O molecules are in 24.0 g H2O?
3
Solution
How many H2O molecules are in 24.0 g H2O?
24.0 g H2O x 1 mole H2O x 6.02 x 1023 H2O molecules 18.02 g H2O 1 mole H2O
= 8.02 x 1023 H2O molecules

Learning Check
If the odor of C6H10S can be detected from 2 x 10-13 g in one liter of air, how many molecules of C6H10S are present?
5
Solution
If the odor of C6H10S can be detected from 2 x 10-13 g in one liter of air, how many molecules of C6H10S are present?
2 x 10-13 g x 1 mole x 6.02 x 1023 molecules 114.21 g 1 mole
= 1 x 109 molecules C6H10S
