Answer:
the percentage concentration of ethanol in the solution is 13.04%.
Explanation:
To find the percentage concentration of ethanol in water, we need to first calculate the total mass of the solution (ethanol + water), and then calculate the mass of ethanol in the solution. Finally, we can calculate the percentage concentration of ethanol in the solution using the following formula:
Percentage concentration = (mass of ethanol / total mass of solution) x 100%
Given that 75 g of ethanol is dissolved in 500 g of water, the total mass of the solution is:
Total mass of solution = mass of ethanol + mass of water
Total mass of solution = 75 g + 500 g
Total mass of solution = 575 g
The mass of ethanol in the solution is simply 75 g. Therefore, we can calculate the percentage concentration of ethanol in the solution as:
Percentage concentration = (mass of ethanol / total mass of solution) x 100%
Percentage concentration = (75 g / 575 g) x 100%
Percentage concentration = 13.04%
Therefore, the percentage concentration of ethanol in the solution is 13.04%.
