Neptune has a mass of 1024 1032 milligrams. Use scientific notation to express the planet's mass in kilograms. 1
Levart [38]

Answer:

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

Step-by-step explanation:

Here, the mass of Neptune  = 1024 1032 milligrams

Also, given:  1  milligram = 0.0000001 kilograms.

or,  1  milligram = 1 \times 10^{(-6)}  kilograms.

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

1024 1032 milligrams = 1024 1032  \times 10^{(-6)}  kilograms.

Now solving  1024 1032  \times 10^{(-6)}  , we get:

1024 1032  \times 10^{(-6)}  =  10.241032 kilograms.

Hence the planet's mass =10.241032 kilograms.
