Well, you should specify what you want to do....

#16%# by mass, by volume, what are you actually doing?

Take #16*g# of the salt, and then dissolve this is #84*mL# of water... And thus by mass...you gots…

#(16*g_"solute")/(16*g_"solute"+84*g_"water")xx100%=16%*"w/w"#...

But you must specify the terms of the question....

prepare 16g of potassium chloride, and then add it into 84g of water
(the amount can vary, but the ratio is constant)

16% by mass means that there are 16g of solute per 100g of solution
