Answer 1

The planet's mass in kilograms are
`=1.024 * 10 ^2^5 Kg`

b.
`=1.024 * 10 ^2^5 Kg`

Step-by-step explanation:

Given:

Mass of Neptune =
`=1.024 * 10 ^3^2 Kg` milligrams

The mass in Kg = 1 milligram

`= 0.0000001 Kg = 1 * 10^ -^7 kg`

Then the the planet's mass in kilograms will be:

`(1.024) * 10^3^2 * (1 * 10^ -^7)`

`=1.024 * 10 ^2^5 Kg`

The planet's mass in kilograms are
`=1.024 * 10 ^2^5 Kg`.
