Answer 1

Answer: a.
`2.33*10^(24)` kilograms

Explanation:

Scientific notation: A mathematical expression used to express a very large or a very small number in a product of a decimal number between 1 and power of 10 .

Given : Jacob learns that the mass of a new planet found in the solar system is 2,330,000,000,000,000,000,000,000 kilograms.

Here, in 2,330,000,000,000,000,000,000,000 (A very large number)

Total digits = 25

Power of 10 = Total digits -1= 25-1=24

In scientific notation:

`2,330,000,000,000,000,000,000,000=2.33*10^(24)`

Hence,
`2.33*10^(24)` kilograms is the mass represented in scientific notation.

Answer 2
