Notes Density The density (ρ) is calculated as the mass (m) divided by the volume (v). the formula for density is: ρ = m v. substituting the given values: ρ = 100 grams 100 cm 3 = 1 g cm 3. so, the density of the rectangular block is 1 g cm 3. calculating the density of liquids. to calculate the density of a liquid, you'll need the following equipment. Density example questions. question 1: a rock has a mass of \text {0.6 kg} and a volume of \text {0.15 m}^3 . calculate it’s density. [2 marks] question 2: a cube box has a density of \text {25 kg m}^3 and a mass of 8 \: \text { kg} . calculate the length of each side of the box. [3 marks]. However, when regarding gases, density is largely affected by temperature and pressure. an increase in pressure decreases volume, and always increases density. increases in temperature tend to decrease density since the volume will generally increase. there are exceptions however, such as water's density increasing between 0°c and 4°c. Enter the weight of the object, changing the unit to kg first, if required. next, click on the volume's unit and change it to cubic inches. input the volume as 47 in³. instantly, our calculator will show you the object's density is 103,870 kg m³.

M = mass. v = volume. example problems: 1. calculate the density in g ml of 30 ml of solution that weighs 120 grams. 2. calculate the density in g ml of 0.4 l of solution weighing 150 grams. 3. calculate the density in g ml of 3000 ml of solution weighing 6 kg. 240 kg m 3 or 14.98 lb ft 3. the volume of a champagne cork is around 37.5 cm 3 and its weight is 9 grams. to calculate the density, divide the weight by the volume: 9 g 37.5 cm 3 = 0.24 g cm 3 = 240 kg m 3.
