A closed container has 4.02 ⋅ 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? 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
