To find how much pure antifreeze must added to the 12L of 40% of antifreeze to obtained 60% solution.
Answer to Problem 7P
The number is 6 L.
Explanation of Solution
Given that 12L of 40% of antifreeze to obtained 60% solution.
Formula:
Suppose the pure antifreeze be
First we need to determine the
Now, the total amount of anti-freeze in the solution is
Similarly, the total amount of antifreeze in the solution will be
Compare equation ( i ) and equation ( ii )
Simplify
Hence, 6 L of pure anti-freeze to the 12L of 40% of antifreeze to obtained 60% solution.
