    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 cm 3 We know, Density = mass / volume = 1200 / 502 g/cm 3 = 2.39 g/cm 3 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/cm 3 Volume of marble = 2 cm 3 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/ cm 3 Weight of Clay = 55 kg or 55*1000 = 55,000 g Space or volume occupied = Weight /density = 55,000/2.39 cm 3 = 23012.55 cm 3 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
