Homework Answers
Yes, a solution can have a weight/volume percentage greater than 100%.
The percent weight per volume can be defined as the grams of solute dissolved in 100 mL of solution. Since, more than 100 g of solute can be dissolved in 100 mL of solution. Therefore in this solution, the percent weight per volume would be greater than 100%.
