•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
