Chapter 4 - Mass, Weight and Density
A beaker of 250 cm3 is fully filled with oil (density = 0.9 g/cm3). The total weight of the filled beaker is 3 N. (Take g = 10 N/kg)
a) Calculate the mass of the oil in the beaker.
b) Calculate the mass of the empty beaker.
a) Density = Mass/ volume
0.9 = m / 250
m = 225g
b) mass of beaker + oil = 3N / 10 N/kg
= 0.3 kg
mass of empty beaker = 0.3 *1000g - 225
