Question

250 ml of ethanol has been dissolved in 850 ml of water. Calculate the volume percentage of the solution​

Answer 1

Example:

Mass % of any component of the solution =

(Mass of the component in the solution / Total mass of the solution) x 100

Other methods are:

Volume percentage:

Volume % of a component =

(Volume of the component/Total volume of the solution) x 100

Mass by volume percentage:

It is the mass of solute dissolved in 100 mL of the solution.

Answer 2

Answer:

30%

Explanation:

Here ethanol is solvent volume of 250ml and solution here is water

So, (250÷850)×100

0.294×100

approximately 30 percentage is volume percentage
