Question

A closed container has 3.06 ⋅ 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?

Answer 1

its math but it wont let me post

Answer 2

answer choices

0.47 grams, because (3.06 + 1.67) ⋅(1023 ⋅10–24) = 4.73 ⋅10–1
5.11 grams, because (3.06 ⋅1.67) ⋅(1023 ⋅10–24) = 5.1102
0.51 grams, because (3.06 ⋅1.67) ⋅(1023 ⋅10–24) = 5.1102 ⋅10–1
4.73 grams, because (3.06 + 1.67) ⋅(1023 ⋅10–24) = 4.73

Answer 3

multiply (# of atoms) * (mass per atom) to get total mass.
