Question

If a sample has a mass of 1.25 × 102 g and a volume of 51 ml, what is its density?

Answer 1

The density of a substance is ratio of the mass the substance has to the volume occupied by that mass of substance. Therefore, this can be written as:
Density = mass / volume
Density = 1.25 x 10² / 51
Density = 2.45 grams / milliliter
