You can put this solution on YOUR website! A pharmacist wishes to mix a solution that is 8% Minoxidil.
She has on hand 80 ml of a 4% solution and wishes to add some 10% solution to obtain the desired 8% solution.
How much 10% solution should she add?
;
let x = amt of 10% solution required
:
.04(80) + .10x = .08(x+80)
;
3.2 + .10x = .08x + 6.4
:
.10x - .08x = 6.4 - 3.2
:
.02x = 3.2
x =
x = 160 ml of 10% solution required
;
;
Check:
.04(80) + .10(160) = .08(160+80)
3.2 + 16 = .08(240)
19.2 = 19.2
