There are several ways to do this because the quality was 50% and 15% concentrations not specified.
ReplyDeleteI assume it is from, say, "100 ml" of each.
To 100 ml of 50% ointment prepared ZnO
Use the 50-ml concentration of 70% ointment
Mixture in 35 ml of base and Drug Free
15 ml of pure ZnO.
(this will make 50 ml of a concentration of 30%, mixed with 50 ml of 70% concentration, a total of 100 one hundred mL, a concentration of 50%.
To prepare 100 ml of 20% conc. ZnO ointment
Take 50 ml of the concentration of ZCO Ointment 15%
Mixture in 45 ml of base and Drug Free
5 ml of pure ZCO.
Thus the concentration of 100 ml of 15% ointment cause ZCO.
