What will be the density of carbon dioxide at 100^@C and 800 mm Hg pressure ?

Answer»


Solution :The molecular mass of `CO_2 = 12 + (2 XX 16) = 44`.
In the present case, `P = 800 " mm Hg " = 800/760 = 1.053` atm
`T= 100^@C = 100 + 273 = 373 K`
`:. ""M =(dRt)/P`
`:. "" d = (MP)/(RT)`
SUBSTITUTING the values, we have
`d= (44 xx 1.053)/(0.0821xx 373) = 1.513g L^(-1)`
