Question

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

Answer 1

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%
