Question

A closed container has 6.08 ⋅ 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?

1.02 grams, because (6.08 ⋅ 1.67) ⋅ (1023 ⋅ 10-24 ) = 10.1536 ⋅ 10–1
0.78 grams, because (6.08 + 1.67) ⋅(1023 ⋅ 10–24 ) = 7.75 ⋅ 10–1
7.75 grams, because (6.08 + 1.67) ⋅ (1023 ⋅ 10–24 ) = 7.75
10.15 grams, because (6.08 ⋅ 1.67) ⋅ (1023 ⋅ 10–24 ) = 10.1536

Answer 1

Answer 2

total weight W is:
\[W = 6.08 \times {10^{23}} \times 1.67 \times {10^{24}}\]

Answer 3

oops...
\[\Large W = 6.08 \times {10^{23}} \times 1.67 \times {10^{ - 24}}\]
