A) Give the mathematical formula for relative density.b) Give the SI unit of density.c) A solid weighs 80 g in air, 64 g in water. Calculate the relative

1) formula of relative density = density of the substance / density of water. 2) S.I.unit of density is kg/m³ 3) given, mass of the object in air = 80 grams mass of the object in water = 64 grams density of water = 1g/cm³ therefore relative density , = density of the substance / density of water = density of the substance / density in water = 80 / 80 - 64 = 80 / 16 = 5 therefore relative density = 5 i hope it helps.......................^_^
