120 g of solution contains 3 g of glucose. determine the mass fraction of the solute.

Given:

m (solution) = 120 g

m (substance) = 3 g

Find:

W =?

Solution:

The formula for solving the problem: W = (m (substance) / m (solution)) x 100%.

We know both the mass of the substance and the mass of the solution. Substitute the values into the formula:

W = (3: 120) x 100 = 2.5%

Answer: 2.5%
