Sample Density Problems and Solutions

To give you a better idea of what density problems look like and how to solve them, here are a few examples:

Problem 1: Calculating Density

A block of metal has a mass of 500 grams and a volume of 100 cubic centimeters. What is its density?

Solution: Density is calculated using the formula:

Density = Mass / Volume

Substituting the given values:

Density = 500 g / 100 cm³ = 5 g/cm³

Problem 2: Determining Mass

A substance has a density of 2 g/cm³ and a volume of 150 cm³. What is its mass?

Solution: Rearranging the density formula to solve for mass:

Mass = Density × Volume

Substituting the given values:

Mass = 2 g/cm³ × 150 cm³ = 300 g
