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?


0.47 grams, because (3.06 + 1.67) ⋅ (10^23 ⋅ 10^-24) = 4.73 ⋅ 10^–1

0.51 grams, because (3.06 ⋅ 1.67) ⋅(10^23 ⋅ 10^–24) = 5.1102 ⋅ 10^–1

4.73 grams, because (3.06 + 1.67) ⋅ (10^23 ⋅ 10^–24) = 4.73

5.11 grams, because (3.06 ⋅ 1.67) ⋅ (10^23 ⋅ 10^–24) = 5.1102

Answer 1

May I help?

Answer 2

yes

Answer 3

Simple multiplication leads to the total mass of all atoms.

"atoms' number*weight of an atom= total mass of the atoms in the container"

Answer 4

\[Total mass=(3.06)10^{23 }*(1.67)10^{–24}=(3.06*1.67)*10^{-1}=0.51102gram\]
So the correct choice will be B (0.51)
