Detailed Solution

Given table shows the mass of the planets, the Sun, and the Moon in our solar system.
The mass of Sun is,
=1,990,000,000,000,000,000,000,000,000,000 kg
Rewrite 1000000000000000000000000000000 as 1030 to write the mass of sun in standard notation, the mass of sun =1.99×1030.
Similarly converting all the masses in standard notation:

Celestial Body

Mass in (kg) in Standard Notation

Sun

1.99×1030

Mercury

3.3×1023

Venus

4.87×1024

Earth

5.97×1024

Mars

6.42×1029

Jupiter

1.9×1027

Saturn

5.68×1026

Uranus

8.68×1025

Neptune

1.028×1026

Pluto

1.27×1022

Moon

7.35×1022

Arranging  from least to greatest.
