Aclosed container has 2.04 ⋅ 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) 0.34 grams, because (2.04 ⋅ 1.67) ⋅ (1023 ⋅ 10−24) = 3.4068 ⋅ 10−1
b) 0.37 grams, because (2.04 + 1.67) ⋅ (1023 ⋅ 10−24) = 3.71 ⋅ 10−1
c) 3.41 grams, because (2.04 ⋅ 1.67) ⋅ (1023 ⋅ 10−24) = 3.4068
d) 3.71 grams, because (2.04 + 1.67) ⋅ (1023 ⋅ 10−24) = 3.71
