Question 826176: a chemist needs 13 liters of a 10% acid solution should be mixed with a 31% solution to get that ( round your answer to the nearest liter)?
Answer by josgarithmetic(39617)   (Show Source):
You can put this solution on YOUR website! Finish the problem description. Does he want 10% acid solution, or does he want to mix 10% acid solution with 31% solution? Does he know how much of each? Does he know how much acid solution he wants when finished?
What must be clearly mentioned are:
Target concentration,
Concentration of the lesser strength material,
Concentration of the greater strength material,
depending on type of situation - Quantity of expected resulting solution -,
Quantity of lesser strength material,
Quantity of greater strength material.
Typically, one or two of those would be UNKNOWN variables.
