A closed container has 6.08 ⋅ 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?

Verified Answer :

Total mass = 6.08 x 10^23 * 1.67 x 10^-24 = 1.01536

Answer:

\(10.1536\times  10^{-1}\approx 1.02\) grams.

Step-by-step explanation:

We have been given that a closed container has \(6.08\times 10^{23}\) atoms of a gas. Each atom of the gas weighs \(1.67\times 10^{-24}\) grams.

To find the total mass, in grams, of all the atoms of the gas in the container, we will multiply number of atoms with mass of each atom.

\(\text{Total mass}=6.08\times 10^{23}\times 1.67\times 10^{-24}\)

Using exponent property \(a^b\times a^c=a^{b+c}\), we will get:

\(\text{Total mass}=6.08\times 1.67\times  10^{23}\times 10^{-24}\)

\(\text{Total mass}=10.1536\times  10^{23+(-24)}\)

\(\text{Total mass}=10.1536\times  10^{-1}\)

\(\text{Total mass}=10.1536\times\frac{1}{10}\)

\(\text{Total mass}=1.01536\)

\(\text{Total mass}\approx 1.02\)

Therefore, the approximate total mass, in grams, of all the atoms of the gas in the container is \(10.1536\times  10^{-1}\approx 1.02\) grams.
