Practical Applications of Density Calculations in Everyday
Scenarios
1. A ball of clay has mass of 1.2kg and volume of 502 cm3(cubed).What is its density in g/cm3?
Answer: Mass of clay = 1.2 kg
= 1.2 * 1000 g [1kg = 1000 g]
= 1200 g
Volume of clay = 502 cm3
We know, Density = mass / volume
= 1200 / 502 g/cm3
= 2.39 g/cm3
2. Using the density of clay that you just calculated, what would be the weight of a marble with volume 2 cm3?
Answer: Density = 2.39 g/cm3
Volume of marble = 2 cm3
Weight or mass of marble = density * Volume
= 2.39 * 2 g
= 4.78 g
3. You have shoveled up 55kg of clay from your backyard. How much space would that much clay occupy in your
wheelbarrow?
Answer: Density of clay = 2.39 g/ cm3
Weight of Clay = 55 kg or 55*1000 = 55,000 g
Space or volume occupied = Weight /density
= 55,000/2.39 cm3
= 23012.55 cm3
4. Whole blood has a density just slightly above that of water, about 1.05g/ml. The average adult has about 5.5l of
blood total. How much does this weigh in g?in kg?
Answer: Density of blood = 1.05 g/ml
Volume of blood = 5.5 l or 5.5*1000 = 5,500 ml
Weight = Density * volume
= 1.05 * 5500 g
= 5575 g
= 5575/1000 kg [1kg = 1000g]
= 5.575 kg
5. Blood is normally collected in "unit" bags of about a pint,475ml. How much would a pint of blood weigh?
Answer: Density of blood = 1.05 g/ml
Volume of blood = 475 ml
Weight of pint of blood = Density * volume
= 1.05 * 475 g
= 498.75 g
6. You've collected a tube of blood that contains 12ml total. How much would that weigh?
Answer: Density of blood = 1.05 g/ml
Volume of blood = 12 ml
Weight of 12 ml of blood = Density * volume
= 1.05 * 12 g
= 12.6 g
