A 1000 ml of solution contains 25% acetic acid by volume after some evaporation 200 ml of the solution has evaporate assuming only the water evaporates what is the new percent by volume concentration of acetic acid in the remaining solution?
Answer (1)
Here's how to solve this problem: 1. Calculate the initial volume of acetic acid: - The solution initially contains 25% acetic acid by volume, so there are 0.25 * 1000 ml = 250 ml of acetic acid. 2. Calculate the remaining volume of the solution: - After evaporation, 200 ml of water has evaporated, leaving 1000 ml - 200 ml = 800 ml of solution. 3. Calculate the new percent by volume concentration: - The volume of acetic acid remains the same (250 ml).- The new concentration is (250 ml / 800 ml) * 100% = 31.25% Therefore, the new percent by volume concentration of acetic acid in the remaining solution is 31.25%.
