Density

• $\rho=$$\frac{m}{V}$

  • Density (kg/m3)
  • Mass (kg)
  • Volume (m3)
• To find the density of a regular solid practical

  • Measure the width, height and length
  • Use a balance to measure the mass
  • divide the mass by volume to find density
• To find the density of a irregular solid practical

  • Use a balance to measure the mass
  • Fill a eureka can with water
  • Submerge the object in the eureka can and collect the displaced liquid in a measuring cylinder
  • Record the volume of displaced water and then calculate the density
• To find the density of a liquid practical

  • Place a measuring cylinder on a balance set to 0
  • Pour 10ml of the liquid in the measuring cylinder and record the mass
  • Pour another 10ml and record the total volume and mass
  • Repeat until the measuring cylinder is full
  • For each measurement find the density and then take an average to get an accurate density
