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
