0.1024 1027
10.24 1025
1024 1023
1024 1026

Answer 1

(b) The planet's mass =10.241032 kilograms.

Explanation:

Here, the mass of Neptune = 1024 1032 milligrams

Also, given: 1 milligram = 0.0000001 kilograms.

or, 1 milligram =
`1 * 10^((-6))` kilograms.

Now, to convert 1024 1032 milligrams in to kilograms, we get:

1024 1032 milligrams =
`1024 1032  * 10^((-6))` kilograms.

Now solving
`1024 1032  * 10^((-6))` , we get:

`1024 1032  * 10^((-6))  =  10.241032` kilograms.

Hence the planet's mass =10.241032 kilograms.
