Problem: Calculate the molality of a solution formed by adding 2.80 g NH4Cl to 16.0 g of water.

FREE Expert Solution

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:


Molality(m)=moles solutekg solvent


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
