Problema Solution
pure acid is to added to a 5% solution to obtain 95L of 34% solution, what amounts of each should be used
Answer provided by our tutors
let
x = L of pure 100% acid
y = L of 5% solution
we need to make 95L of 34% solution:
x + y = 95
1.00x + 0.05y = 0.34*95
by solving the above system of equations we find:
x = 29 L
y = 66 L
click here to see the step by step solution of the system of equations:
29 liters of 100% pure acid and 66 liters of 5% solution should be used for the mix.
