An ideal mixture of liquids A and B with 2 moles of A and 2 moles of B has a total vapour pressure of 1 atm at a certain temperature. Another mixture with 1 mole of A and 3 moles of B has a vapour pressure greater than 1 atm. But if 4 moles of C are added to the second mixture, the vapour pressure comes down to 1 atm. Vapour pressure of C, \[P_{c}^{0}\]=0.8 atm. Calculate the vapour pressures of pure A and pure B

• A. \[P_{A}^{o}\]=1.4 atm, \[P_{B}^{o}\]=0.7 atm
• B. \[P_{A}^{o}\]=1.2atm, \[P_{B}^{o}\]=0.6atm
• C. \[P_{A}^{o}\]=1.4atm, \[P_{B}^{o}\]=0.6atm
• D. \[P_{A}^{o}\]= 0.6 atm, \[P_{B}^{o}\]= 1.4 atm
