Question

114 g KCl in 598 g H2OCalculate the concentration of each solution in mass percent.

Answer 1

We need to use the formula of mass percent, which is:

`\text{mass percent=}\frac{mass\text{ of solute}}{mass\text{ of solution}}\cdot100,`

Our solute is 114 g of KCl and the solution is the sum of the solute and solvent (water). We replace these amounts on the formula:

`\text{mass percent=}(114)/(114+598)\cdot100=16.01;`

So, the concentration of 114g of KCl in 598g of water is 16.01%
