10ml of liquid xarbon disulphide(specific gravity 2.63)is burnt in oxygen.Find the volume of the resulting gases measured at STP. a)23.25L b)22.26L c)23.50L. d)20.08L

plz explain with meaning of specific gravity

Your Answer

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
