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

Feb 24, 2017

Mass $1000$ atoms of gold would be $3.25 \times {10}^{- 19}$ grams

#### Explanation:

As mass of an atom of gold has a mass of approximately $3.25 \times {10}^{- 22}$ grams,

Mass $1000$ atoms of gold would be

$3.25 \times {10}^{- 22} \times 1000$

= $3.25 \times {10}^{- 22} \times {10}^{3}$

= $3.25 \times {10}^{\left(- 22 + 3\right)}$

= $3.25 \times {10}^{- 19}$ grams
