The density of an object can be found by dividing the mass of the object by its volume. The volume of the Earth is 2.1\times 10^{11}2.1×10
11
cubic meters and its mass is 7\times 10^{24}7×10
24
kilograms. What is the density of the Earth in kilograms per cubic meter? Answer should be in scientific notation with first number being rounded to the hundredths place.
