Question

A pharmacy technician is making a 50% solution, how many mL of a 38% stock solution should be added to one pint of a 82% solution? ( just need to know how to set this problem up please)

Answer 1

just keep track of the amount of solute present. The amounts must add up to the total in the final solution. Remember to watch the units; a pint is 473mL.

.38x + .82(473) = .50(x+473)
