Solve this: Q. If P ° and P are the vapour pressure of solvent and solution, n1 and n2 are the moles of solute and solvent, then ( 1 ) P ° = P n 2 n 1 + n 2 ( 2 ) P = P ° n 2 n 1 + n 2 ( 3 ) P ° = P n 1 n 1 + n 2 ( 4 ) P ° = P × n 1 Share with your friends Share 3 Ashwini Kumar Mishra answered this Dear student , Regards 0 View Full Answer
