Answer 1

The planet's mass in kilograms are $=1.024 \times 10 ^2^5 Kg$

b. $=1.024 \times 10 ^2^5 Kg$

Explanation:

Given:

Mass of Neptune = $=1.024 \times 10 ^3^2 Kg$ milligrams

The mass in Kg = 1 milligram

$= 0.0000001 Kg = 1 \times 10^ -^7 kg$

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

$(1.024) \times 10^3^2 \times (1 \times 10^ -^7)$

$=1.024 \times 10 ^2^5 Kg$

The planet's mass in kilograms are $=1.024 \times 10 ^2^5 Kg$.
