Solution

Sure, here are the steps to calculate the mass percent (m/m) of a solution:

  1. First, you need to find the total mass of the solution. This is done by adding the mass of the solute (KCl) to the mass of the solvent (H2O). In this case, it would be 25 g (KCl) + 125 g (H2O) = 150 g.

  2. Next, you calculate the mass percent. The formula for mass percent is (mass of solute / total mass of solution) * 100.

  3. Substituting the given values into the formula, we get (25 g / 150 g) * 100 = 16.67%.

So, the mass percent (m/m) of the solution is 16.67%.
