What is the vapor pressure at 23 degree C of a solution of 1.20g of naphthalene, C10H8 in 25.6 g of benzene, C6H6? The vapor pressure of naphthalene can be neglected. Calculate the vapor-pressure lowering the solution

Answer 1

Do you have the normal vapor pressure of benzene at that temperature? Or have you been told to look it up?

Answer 2

92.40 [mmHg]

Answer 3

delta P_solvent(lowering) = X_soluteP^o_solvent
