1.	What will be the pressure exerted by a mixture of 3.2 g of methane and 4.4 g of carbon dioxide contained in a 9 dm^(3) flask at 27 ^(@)C ?
Answer» Solution :Total no. of moles (n) present in the GASEOUS mixture `=(3.2)/16 + (4.4)/44 = 0.3` `( :." mol. mass of " CH_4 = 16 " and mol. mass of " CO_2 = 44)` ACCORDING to the gas equation, `PV = nRT` `:. "" Pxx 9 = 0.3 xx 8.314 xx 10^3 xx 300` `( :. R = 8.314 xx 10^3 " Pa " dm^3 k^(-1) mol^(-1)`) or `P= (0.3 xx 8.314 xx 10^3 xx 300)/9` `=8.314xx10^4 Pa`
