What is the %v/v concentration of a solution made by adding 25 ml of acetone to 75 ml of water?
Looks like 1:3 acetone:water
or, 1:4 = 25% acetone in all.
thanks dude!
To find the %v/v concentration of a solution, you divide the volume of the solute (in this case, acetone) by the total volume of the solution and then multiply by 100.
Step 1: Calculate the volume of the solute (acetone).
Given that 25 mL of acetone is added to the solution, the volume of the solute is 25 mL.
Step 2: Calculate the total volume of the solution.
The total volume of the solution is the sum of the volume of the solute (acetone) and the volume of the solvent (water). In this case, the volume of water is 75 mL.
Total volume of the solution = volume of acetone + volume of water
Total volume of the solution = 25 mL + 75 mL
Total volume of the solution = 100 mL
Step 3: Calculate the %v/v concentration.
%v/v concentration = (volume of solute / total volume of solution) × 100
%v/v concentration = (25 mL / 100 mL) × 100
%v/v concentration = 25%
Therefore, the %v/v concentration of the solution made by adding 25 mL of acetone to 75 mL of water is 25%.
To calculate the %v/v (volume/volume) concentration of a solution, you need to divide the volume of the solute (acetone) by the total volume of the solution (acetone + water), and then multiply by 100 to get the percentage.
In this case, you added 25 ml of acetone to 75 ml of water, giving a total volume of the solution of 25 ml + 75 ml = 100 ml.
To find the %v/v concentration of acetone, divide the volume of acetone (25 ml) by the total volume of the solution (100 ml), and multiply by 100:
%v/v concentration of acetone = (25 ml / 100 ml) * 100
Simplifying the equation:
%v/v concentration of acetone = 25%
So, the %v/v concentration of the solution made by adding 25 ml of acetone to 75 ml of water is 25%.
