Classwork/Homework 3.3 QUIZ, Friday April 11 3.3 Activity: The Evaporation of Water (page 129) 3.3 Review Problems (page 130 – 131): all even 3.3 QUIZ, Friday April 11

EXAMPLE 1 If you will distribute 1 mole of dollars evenly to each of the 4.5 x 109 people on Earth and each person spend one thousand dollars each second, day and night. What percentage of each person’s wealth will have been spent after one year? 0.2357%

EXAMPLE 2 The total land area of the earth is 1.49 x 108 km2. The cross – sectional area of a penny is 3.61 cm2 (1 km2 = 1x1010 cm) and the thickness of a penny is 1.50 mm. If a mole of pennies is distributed evenly over the total land area of the earth, how thick a layer will be formed?
