What is the density of a fuel of relative density 0.72? [Density of water = 1000kg m-3]
Answer Details
Relative density, also known as specific gravity, is defined as the ratio of the density of a substance to the density of a reference substance. In this case, the reference substance is water, which has a density of 1000 kg/m3. Therefore, the density of the fuel can be calculated by multiplying the relative density by the density of water: Density of fuel = Relative density x Density of water Density of fuel = 0.72 x 1000 kg/m3 Density of fuel = 720 kg/m3 Hence, the density of the fuel is 720 kg/m3. Therefore, the correct option is: 720 kgm-3
