Question

A closed container has 7.05 ⋅ 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?

A. 0.87 grams, because (7.05 + 1.67) ⋅ (1023 ⋅ 10-24 ) = 8.72 ⋅ 10-1

B.1.18 grams, because (7.05 ⋅ 1.67) ⋅ (1023 ⋅ 10-24 ) = 11.7735 ⋅ 10-1

C. 8.72 grams, because (7.05 + 1.67) ⋅ (1023 ⋅ 10-24 ) = 8.72

D. 11.77 grams, because (7.05 ⋅ 1.67) ⋅ (1023 ⋅ 10-24 ) = 11.7735 Question 16
