We’re being asked to determine the molality of a solution formed when 2.80 g NH4Cl is added to 16.0 g of water.
Recall that molality is the ratio of the moles of solute and the mass of solvent (in kilograms).
In other words:
For this problem, we need to do the following steps:
Step 1: Determine the mol of solute
Step 2: Determine the kg of solvent
Step 3: Determine the molality
Calculate the molality of a solution formed by adding 2.80 g NH4Cl to 16.0 g of water.
