If 33.6 g of kcal are dissolved in 192 g of water, what is the concentration of the solution in percent by mass?

To calculate the Percentage by mass of KCl that dissolve in water is calculated as

first getting the total mass of KCl and that of water

that is 33.6 + 192=225.6grams

the percentage by mass is therefore calculate as The mass of KCl divided by total multiply by 100

that is (33.6/225.6) x100=14.9%
