Step-by-step explanation:
We have been given that the mass of Earth is
kg. The mass of the Moon is
kg.
To find the total mass we will add mass of Earth and Moon.
First of all let us convert the given masses in standard form.



Therefore, the mass of Earth and Moon is 6045000000000000000000000 kg.
About 7
