Isopropyl alcohol and n-propyl alcohol, both have the same molecular formula C_3H_8O . A solution of the two, that is, 25% isopropyl alcohol by mass, has a total vapour pressure of 0.09 atm at a given temperature. A solution of the two, that is, 75% isopropyl alcohol by mass, has a total vapour pressure of 0.12 atm at the same temperature. Find the vapour pressures of the pure alcohols at this temperature.

1.	Isopropyl alcohol and n-propyl alcohol, both have the same molecular formula C_3H_8O . A solution of the two, that is, 25% isopropyl alcohol by mass, has a total vapour pressure of 0.09 atm at a given temperature. A solution of the two, that is, 75% isopropyl alcohol by mass, has a total vapour pressure of 0.12 atm at the same temperature. Find the vapour pressures of the pure alcohols at this temperature.
Answer» SOLUTION :0.135 ATM, 0.075 atm
