Use the formula: mass = density × volume
Use the formula: mass = force ÷ acceleration
Use a balance scale to compare with known masses
Use a spring scale to find weight, then divide by gravitational acceleration: mass = weight ÷ g
Use the formula: mass = number of moles × molar mass
Use the formula: mass = concentration × volume for solutions
Use the formula: mass = momentum ÷ velocity
Use the formula: mass = kinetic energy × 2 ÷ velocity²
Use the formula: mass = force × time ÷ change in velocity
Measure the object and apply the appropriate physical relation
