Question

A closed container has 4.02 ⋅ 1023 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?

6.71 grams, because (4.02 ⋅ 1.67) ⋅ (1023 ⋅ 10–24) = 6.7134
5.69 grams, because (4.02 + 1.67) ⋅ (1023 ⋅ 10–24) = 5.69
0.67 grams, because (4.02 • 1.67) ⋅ (1023 ⋅ 10–24) = 6.7134 • 10–1
0.57 grams, because (4.02 + 1.67) ⋅ (1023 ⋅ 10–24) = 5.69 ⋅ 10–1

Answer 3

\[(4.02*10^{23})*(1.67*10^{-24})=(4.02*1.67)*10^{23-24}=(4.02*1.67)*10^{-1}=?\]
