Question 11.4: CALCULATING THE MOLALITY OF A SOLUTION What is the molality ...

CALCULATING THE MOLALITY OF A SOLUTION

What is the molality of a solution made by dissolving 1.45 g of table sugar (sucrose, $C_{12}H_{22}O_{11}$ ) in 30.0 mL of water? The molar mass of sucrose is 342.3 g/mol.

STRATEGY
Molality is the number of moles of solute per kilogram of solvent. Thus, we need to find how many moles are in 1.45 g of sucrose and how many kilograms are in 30.0 mL of water.
