Phenylcarbinol is used in nasal sprays as a preseriative. A solution of 0.52g of the compound in 25.0g of water has a melting point of -0.36C.

Question

What is the molar mass of phenylcarbinol?

Answer 1

delta T = Kf*m
You know delta T and Kf for water, solve for molality.
m = mols/kg solvent
You know m and kg solvent, solve for moles.
Finally, moles = grams/molar mass.
You know moles and grams, solve for molar mass.

Answer 2

Thank you !
