Question

The mass of Earth is approximately 5.97 x 10^24 kilograms . The mass of Venus is approximately 4,870,000,000,000,000,000,000,000 kilograms . What is the difference between the approximate masses , in kilograms , of Earth and Venus ? Express your answer in scientific notation.

Answer 1

`1.1*10^(24)\ kg`

Explanation:

step 1

we have

The mas of Earth is approximately

`5.97*10^(24)\ kg`

The mass of Venus is approximately

`4,870,000,000,000,000,000,000,000\ kg`

Convert to scientific notation

`4.87*10^(24)\ kg`

step 2

Find the difference

`5.97*10^(24)\ kg-4.87*10^(24)\ kg=1.1*10^(24)\ kg`
