Question

Cagedie changes saved 9 (01.07 HC) A closed container has 4.02 - 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 point)

Answer 1

The container has

`4.02*10^(23)`

atoms, and each one weighs

`1.67*10^(-24)`

grams.

Then, the total weight is

`\begin{gathered} (4.02*10^(23))(1.67*10^(-24))=(4.02*1.67)*10^(23-24)=6.7*10^(-1) \\ =0.67 \end{gathered}`

Then, the answer is the second one, 0.67 grams.
