Best ResponseYou've already chosen the best response.1if you have a 15% by mass solution of KCl, it means you have 15 g of KCl in 100 g of solution (meaning you have 85 grams of water in 100 grams of solution) 100g15g=85 g so in 200 g of solution you have 30 grams of KCl, right?

Best ResponseYou've already chosen the best response.1Find out 15% of 200g 200/100x15 = 30g of KCl 200g30g = 170g of H2O So surely it would be 170g of water by mass and 30g of KCl
