9.25% KCl solution is prepared by dissolving enough of the salt to give 100.0 g of solution. What is the mass of water required?
Answered by DrBob222
% w/w = [(mass solute)/(total mass soln)]*100 = ?
mass soln is mass solute + mass solvent. If the total is 100 g and mass solute is 9.25 g, what is mass solvent.
