Solutions - 1
•A.Basic ways of measuring concentration of solutions:
•1.Weight per unit weight (w/w)
•2.Weight per unit volume (w/v)
•3.Volume per unit volume (v/v)
•B.Calculations of solutions:
•1.Weight per unit weight (w/w)
•Make 500 gm of a 10% NaCl aqueous solution
•500 gm x 0.10 = 50 gm
•
•then add the 50 gm NaCl to 450 gm H2O
