BACE Practice Problem 10: How to Calculate Mass for a Weight/Volume (w/v) % Solution

In this tutorial, we break down how to find the mass of a solute using the weight/volume percent (w/v) formula. This is a common chemistry calculation used in labs and exams to determine how much of a solid substance is needed to create a specific concentration.

We solve Practice Problem #10: "Calculate the mass in g of sucrose required to make 125 mL of a 15.5% (w/v) sucrose solution. Record the correct amount, rounded to one decimal place."

What you’ll learn in this video:

The definition of w/v percent concentration.

How to rearrange the concentration formula to solve for mass.

A step-by-step walkthrough of the math.
