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
