We're being asked to determine the molality of methanol in a mixture of water and methanol.
Recall that molality can be calculated as:
Hence we have to calculate for moles of CH3OH and kg of water using the mass and molar mass provided
A solution is made containing 12.6 g of methanol CH 3OH (32.04 g/mol) in 154 g of water. H20 (18.02 g/mol)
c) Calculate the molality of methanol:
a. 2.55 m
b. 0.944 m
c. 1.62 m
d. 1.79 m
e. 0.272 m
