  • 1 ml of CS2 weighs 2.63 gSo, 10 ml of CS2 weighs 2.63×10=26.3 g CS2   +   3O2  ?   CO2   + 2SO2 76 g                          22.4L     44.8 L76 g CS2 yields 67.2 L of a mixture of CO2 and SO2 at STPTherefore, 26.3 g o CS2 will yield 67.276×26.3=23.26 L The specific gravity is the ratio between the density of an object, and a reference substance. Usually our reference substance is water It is just like relative density
