a) Density

a) density; ρ = m/v

density = the mass of an object per unit volume

ρ = m/v

• density (kgm^-3) = mass (kg) / volume (m³)

to determine the density of an irregularly shaped object

• measure the mass of the object using a digital balance

• measure the volume of water in a measuring cylinder

• submerge the object in the water

• measure the new volume of the water

• volume difference = volume of the object

• ρ = m/v
