if 80 g of nacl is added to 640 g of water. find the concentration
Mass of solute = 80 g
Mass of solvent = 640 g
Therefore , mass of solution = solute + solvent
= 80 g + 640
= 720 g
Concentration of solution = Mass of solute* 100 / Mass of solution
= 80 * 100 / 720
= 100 / 9
= 11.11 %
Mass of solvent = 640 g
Therefore , mass of solution = solute + solvent
= 80 g + 640
= 720 g
Concentration of solution = Mass of solute* 100 / Mass of solution
= 80 * 100 / 720
= 100 / 9
= 11.11 %
