To find: Critical analysis of what is wrong with the given problem.
Explanation of Solution
Given information:
Some amount of
Calculation:
As per the given information −
Some amount of
In this problem two lower concentration of ethanol are mixed to make a higher concentration of ethanol solution. This is not possible. When two different concentrations of solutions are mixed, the mixture solution becomes a solution of intermediary concentration.
If we try to solve this, then it will result in invalid mathematical equation.
Let us suppose
So total amount of pure ethanol can be written mathematically as below −
Since amount cannot be negative. Therefore, given problem is wrong.
