Question

how much water should be added to 15 gram of salt to obtain 15% solution ​

Answer 1

Answer:

Mass of solute = 15g

   Mass of solvent = 15 + X

   Concentration of solution = (Mass of solute / Mass of solution) X 100

                                 15 = (15/15+X) x 100

                           15 + X = (15/15) x 100

                                  X = 100 - 15

                                  X = 85 g
