Question

What is the molality of a solution containing 75.5 grams sucrose in 400.0 grams water?

Answer 1

step 1: calculate the molar mass of solute.

molar mass of solute = (12.01 g/mol × 12) + (1.008 g/mol × 22) + (16.00 g/mol × 1

molar mass of solute = 342.296 g/m

step 2: calculate the number of moles of solute.ol1)

moles of solute = 0.22056933 mol

Step 3: Calculate the molality of solution.
