Express mass of the Earth in unit of M. Take ME = 6 x 1024kg.

To express the mass of the Earth in units of M, we need to convert the given mass from kilograms to the desired unit.

Given:
Mass of the Earth (ME) = 6 x 10^24 kg

The unit M is not specified in the question, so we will assume it to be a non-standard unit. To express ME in units of M, we can follow these steps:

Step 1: Determine the conversion factor from kilograms (kg) to the unit M.
Since the unit M is non-standard and its conversion is not provided, we cannot directly convert kg to M.

Step 2: Given that the unit M is non-standard, let's say it represents a certain number of kilograms. For example, if we assume that 1 M = 10^22 kg, we can use this conversion ratio to convert ME to M.

Conversion: 1 M = 10^22 kg

Step 3: Now, multiply ME (in kg) by the conversion factor to obtain the mass of the Earth in units of M:

Mass of the Earth (M) = ME (kg) × (1 M / 10^22 kg)

Substituting the given value for ME:

Mass of the Earth (M) = 6 x 10^24 kg × (1 M / 10^22 kg)

Simplifying the expression:

Mass of the Earth (M) = (6 x 10^24) / (10^22) M
Mass of the Earth (M) = 6 x 10^2 M

Therefore, the mass of the Earth can be expressed as 6 x 10^2 M in the assumed non-standard unit M.
