Here is the answer for the question – Suppose that you add 22.6 g of an unknown molecular compound to 0.250 kg of benzene, which has a. You’ll find the correct answer below
Suppose that you add 22.6 g of an unknown molecular compound to 0.250 kg of benzene, which has a
Kf of 5.12oC/m. With the added solute, you find that there is a freezing point depression of 3.30oC compared to pure benzene.
What is the molar mass (in g/mol) of the unknown compound?
The Correct Answer is
140.37m=ΔTf/iKf=3.30∘C/(1)(5.12∘C)divide the mass of the sample by the moles to find the molar mass.
Reason Explained
140.37m=ΔTf/iKf=3.30∘C/(1)(5.12∘C)divide the mass of the sample by the moles to find the molar mass. is correct for Suppose that you add 22.6 g of an unknown molecular compound to 0.250 kg of benzene, which has a
