The volume of water needed to create a 2.4 molar solution with 19.4 moles of ammonia crystals is 8.1 liters.

Explicación

## Step 1The problem involves the concept of molarity in chemistry. Molarity (M) is defined as the number of moles of solute divided by the volume of the solution in liters. The formula for molarity is:### ## Step 2We are given the molarity (M), the number of moles of solute (n), and we need to find the volume of the solution (V). We can rearrange the molarity formula to solve for volume:### ## Step 3Substitute the given values into the formula:### ## Step 4Calculate the volume:### ## Step 5The problem asks for the answer using 2 significant figures. Therefore, we round the calculated volume to 2 significant figures.###
