Question

Show, in a step by step fashion, your calculations to determine the percent

Answer 1

The percent  by volume of a solution : 19.23%

Further explanation

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 :

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