Question

A closed container has 3.06 • 10^23 atoms of a gas. Each atom of the gas weighs 1.67 • 10^–24 grams. Which of the following shows and explains the approximate total mass, in grams, of all the atoms of the gas in the container?

Answer 1

0.47 grams, because (3.06 + 1.67) • (10^23 • 10^–24) = 4.73 • 10^–1
0.51 grams, because (3.06 • 1.67) • (10^23 • 10^–24) = 5.1102 • 10^–1
4.73 grams, because (3.06 + 1.67) • (10^23 • 10^–24) = 4.73
5.11 grams, because (3.06 • 1.67) • (10^23 • 10^–24) = 5.1102^
