Practical Applications of Density Calculations in EverydayScenarios1. A ball of clay has mass of 1.2kg and volume of 502 cm3(cubed).What is its density ing/cm3?Answer: Mass of clay = 1.2 kg= 1.2 * 1000 g [1kg = 1000 g]= 1200 gVolume of clay = 502 cm3We know, Density = mass / volume= 1200 / 502 g/cm3= 2.39 g/cm32. Using the density of clay that you just calculated, what would be the weight of a marblewithvolume 2 cm3?Answer:Density = 2.39 g/cm3Volume of marble = 2 cm3Weight or mass of marble = density * Volume= 2.39 * 2 g= 4.78 g3. You have shoveled up 55kg of clay from your backyard. How much space would that much clay occupy in yourwheelbarrow?Answer:Density of clay = 2.39 g/ cm3Weight of Clay = 55 kgor 55*1000 = 55,000 gSpace or volume occupied = Weight /density= 55,000/2.39 cm3= 23012.55 cm34. Whole blood has a density just slightly above that of water, about 1.05g/ml. The average adult has about 5.5l ofblood total. How much does this weighin g?in kg?Answer:Density of blood = 1.05 g/mlVolume of blood = 5.5 l or 5.5*1000 = 5,500 mlWeight = Density * volume= 1.05 * 5500 g=5575 g= 5575/1000 kg [1kg = 1000g]=5.575 kg5. 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/mlVolume of blood= 475 mlWeight of pint of blood =Density * volume= 1.05 * 475 g=498.75 g6. You've collected a tube of blood that contains 12ml total. How much would that weigh?Answer:Density of blood = 1.05 g/mlVolume of blood= 12 mlWeight of 12 ml of blood =Density * volume= 1.05 * 12 g=12.6g
