🤓 Based on our data, we think this question is relevant for Professor Bindell's class at UCF.

Solution: A solution was prepared by mixing 50.00 mL of 0.100 M HNO 3 and 100.00 mL of 0.200 M HNO3. Calculate the molarity of the final solution of nitric acid.

Problem

A solution was prepared by mixing 50.00 mL of 0.100 M HNO 3 and 100.00 mL of 0.200 M HNO3. Calculate the molarity of the final solution of nitric acid.

Solution

When we mix two solutions of differing concentrations, the final concentration become smaller than the initial concentration because of dilution resulting from the increase in total volume.

We first need to calculate the moles of HNO3 in the original solutions. Recall that molarity is:
