Question

An atom of gold has a mass of approximately `3.25 x 10^-22` grams. What is the mass 1000 atoms of gold?

Answer 1

Mass `1000` atoms of gold would be `3.25xx10^(-19)` grams

Explanation:

As mass of an atom of gold has a mass of approximately `3.25xx10^(-22)` grams,

Mass `1000` atoms of gold would be

`3.25xx10^(-22)xx1000`

= `3.25xx10^(-22)xx10^3`

= `3.25xx10^((-22+3))`

= `3.25xx10^(-19)` grams
