1.	A mixture of CO and CO_2 is found to have a density of 1.5 g/L at 30^(@)C and 740 torr . What is the composition of the mixture .
Answer» `CO = 0.3575 , CO_2 = 0.64225` `CO = 0.64225 , CO_2 = 0.3575` `CO = 0.500 , CO_(2) = 0.500` `CO = 0.2500 , CO_(2) = 0.7500` Solution :Useexpression , ` d = (PM)/(RT)` `implies M = (DRT)/(P) = (1.5 xx 0.0821 xx 303 xx 76)/(74)` `= 38.276` Let one mole of the MIXTURE CONTAIN , N mole of CO and (1 -n) mole of `CO_(2)` `n xx 28 + (1 - n) xx 44 = 1 xx 38.276` [Molecular weights , `CO = 28 CO_(2) = 44]` since n= 0.35775 Number of moles `CO = 0.35775` & number of moles of `CO_(2) = 0.64225`
