1:4 Bctrim solution when converted in the % strength= (1/4)x100
= 25 %
Then applying the dilution formula:
SdilutionX Vdilution = SstockX Vstock
Where Sdilution= strength of diluted/ required solution
Vdilution= volume of diluted/ required solution
Sstock= strengh of stock solution
Vstock = Required volume of stock solution
SdilutionX Vdilution = SstockX Vstock
25 X 36 = 30% X Vstock
the volume required in ml of stock solution will be Vstock= (25 X 36)/ 30
=900/30
= 30 ml
