oles in 4.9g = grams/molar mass = ? m = molality = mols/kg solvent delta T = Kf*m. Solve for delta T and subtract from the normal freezing point of H2O (0C) to find the new freezing point. pi = MRT M is molarity but in dilute solutions M and m are almost
i have another question.
i got 2.002 atm is that right
psoln = XH2OPoH2O Then XH2O + XCH4N2O = 1. Solve for XCH4N2O im confused still
i still don't get it sir
