If concentration by mass of 600 g NaCl solution is 40 %, find the amount of solute by mass
Question
If concentration by mass of 600 g NaCl solution is 40 %, find the amount of solute by mass.
Solution
The concentration by mass is given by the formula:
Concentration by mass = (Mass of solute / Mass of solution) * 100%
We know the mass of the solution (600g) and the concentration by mass (40%). We can rearrange the formula to solve for the mass of the solute:
Mass of solute = (Concentration by mass * Mass of solution) / 100%
Substituting the given values:
Mass of solute = (40 * 600) / 100 = 240g
So, the amount of solute by mass in the solution is 240g.
