The percent  by volume of a solution : 19.23%

<h3>Further explanation</h3>

Given

50 ml of ethanol

210  ml of water

Required

The percent  by volume of a solution

Solution

Percent Volume (% v/v) : volume (ml) of solute/100 ml of solution ⇒ ratio of the volume of the solute to total volume of the solution

\tt \%solute(v/v)=\dfrac{solute~volume}{solution~volume}\times 100\%

solute= Ethanol

solvent=water

Solution = solute+solvent

Total volume of the solution :

\tt =volume~of~Ethanol+solume~of~water\\\\=50~ml+210~ml\\\\=260~ml

Percent by volume :

\tt \%volume=\dfrac{50}{260}\times 100\%\\\\\%volume=19.23\%
