If the percent (mass/mass) for a solute is 6% and the mass of the solution is 300 g., what is the mass of solute in solution?

(mass solute/mass soln) = 0.06

To find the mass of the solute in the solution, you need to use the formula:

Mass of solute = Percent solute × Mass of solution / 100

Given:
Percent (mass/mass) = 6%
Mass of solution = 300 g

Substituting the values into the formula, we have:

Mass of solute = 6 × 300 / 100

Now, it's time to calculate:

Mass of solute = 18 g

Therefore, the mass of the solute in the solution is 18 grams.
