Q4
A gasesous mixture contains three gases N2, O2 and CO2 with a total number of moles of 10 and total pressure of 10 atm. The partial pressure of N2 is 3 atm . The pressure is reduced to 9 atm if the gases is passed through alkaline pyrogallol. If CO2 has molecular weight of 44 g/mol. Then, the weight of CO2 (in grams) present in the mixture will be:
