A closed container has 2.04 • 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?

A. 0.34 grams, because (2.04 •1.67) • (10^23 • 10^–24) = 3.4068 • 10^ –1
B. 0.37 grams, because (2.04 + 1.67) • (10^23 • 10^–24) = 3.71 • 10^ –1
C. 3.41 grams, because (2.04 •1.67) • (10^23 • 10^–24) = 3.4068
D. 3.71 grams, because (2.04 + 1.67) • (10^23 • 10^–24) = 3.71

A.    0.34 grams, because (2.04 •1.67) • (10^23 • 10^–24) = 3.4068 • 10^ –1
	B.     0.37 grams, because (2.04 + 1.67) • (10^23 • 10^–24) = 3.71 • 10^ –1
	C.     3.41 grams, because (2.04 •1.67) • (10^23 • 10^–24) = 3.4068
	D.     3.71 grams, because (2.04 + 1.67) • (10^23 • 10^–24) = 3.71
