Problema Solution
a laboratory employ is mixing 10% solution with a 4% solution how much of each solution is needed to make a 500 milliliter solution of a 6% solution
Answer provided by our tutors
let 'x' represent the amount of 10% solution, then '500-x' represents the amount of 4% solution
500*0.06 = 0.1x + 0.04(500-x)
solving for 'x' we have x=166.7
500-166.7 = 333.3
166.7 ml of 10% solution should be mixed with 333.3 ml of 4%
