Water is added to a measuring cylinder containing 100 cm3 of liquid paraffin. (the density of paraffin is 0.80 g/ cm3 and that of the water is 1.0 g / cm3 .) as the water is added, the level of the paraffin rises to 150 cm3 . the paraffin and water do not mix. what finally is the total mass of liquid in the measuring cylinder?

The total of the liquid in the measuring cylinder given the data from the question is 130 g

What is density?

The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as

Density = mass / volume

How to determine the mass of paraffin

  • Density of paraffin = 0.80 g/cm³
  • Volume of paraffin = 100 cm³
  • Mass of paraffin =?

Mass = Density × Volume

Mass of paraffin = 0.8 × 100

Mass of paraffin = 80 g

How to determine the mass of water

  • Density of water = 1 g/cm³
  • Volume of paraffin = 100 cm³
  • Volume of paraffin + water = 150 cm³
  • Volume of water = 150 – 100 = 50 cm³
  • Mass of water =?

Mass = Density × Volume

Mass of water = 1 × 50

Mass of water = 50 g

How to determine the mass of the mixture

  • Mass of water = 50 g
  • Mass of paraffin = 80 g
  • Mass of mixture =?

Mass of mixture = Mass of paraffin +  Mass of water

Mass of mixture = 80 + 50

Mass of mixture = 130 g
