The vapour density of a gas is 8. What would be the volume occupied by 24.0 g of the gas at STP ? |
|
Answer» Given (Vapour Density) V.D. = 8 Mol.wt = 2 x V.D.= 2 x 8 = 16 No. of moles in 24.0 g of gas = wt/mol.wt = 24/16 = 1.5 moles At s.T.P., 1 mole of a gas occupies 22.4 l 1.5 moles (or 24.0 g) of the gas will occupy = (22.4 x 1.5)/1 = 33.6 l |
