Calculate weight/volume percent from solute mass and final solution volume, or solve for required mass or volume with automatic metric unit conversions.

Required: solute mass and final solution volume.
Use the final solution volume after dissolving and bringing to volume.
Weight/volume concentration
% w/v means grams of solute per 100 mL of final solution. It is not interchangeable with % w/w or % v/v without additional density information.

Weight Volume Percent Formula

The following two example problems outline the steps and information needed to calculate the Weight Volume Percent.

WVP = W / V * 100

Variables:

  • WVP is the Weight Volume Percent (%)
  • W is the total weight (g) 
  • V is the total volume (mL) 

To calculate the weight volume percent, divide the weight by the volume, then multiply by 100.

How to Calculate Weight Volume Percent?

The following steps outline how to calculate the Weight Volume Percent.

Example Problem #1:

  1. First, determine the total weight (g).
    • The total weight (g) is given as:: 12.
  2. Next, determine the total volume (mL).
    • The total volume (mL) is provided as: 100.
  3. Finally, calculate the Weight Volume Percent using the equation above: 

WVP = W / V * 100

The values provided above are inserted into the equation below and computed.

WVP = 12 / 100 * 100 = 12.00 (%)


Example Problem #2: 

For this problem, the variables required are provided below:

total weight (g) = 13

total volume (mL) = 50
