Question

A closed container has 3.06 • 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?

ANSWER CHOICES:
A. 0.47 grams, because (3.06 + 1.67) • (10^23 • 10^–24) = 4.73 • 10^–1

B. 0.51 grams, because (3.06 • 1.67) • (10^23 • 10^-24) = 5.1102 • 10^-1

C. 4.73 grams, because (3.06 + 1.67) • (10^23 • 10^–24) = 4.73

D. 5.11 grams, because (3.06 • 1.67) • (10^23 • 10^–24) = 5.1102

Hmm, I can't say I know how to do this one off the top of my head. After researching it, I found a very similar question: http://openstudy.com/study#/updates/55788155e4b0499ad80c923c

Answer 3

Oh wait -- I think I get it. I believe you just need to multiply them together.
It's equivalent to asking:
You have 2 blocks of wood weighing 5 pounds, what's the total weight?
5 x 2 = 10 pounds.
