3.5 litres of ethanol is present in 15 litres of an aqueous solution of ethanol. Calculate volume percent of ethanol solution.
बेरीज
उत्तर
Volume of ethanol (solute) = 3.5 litre
Volume of aqueous solution = 15 litre
The volume of the solution = `"Volume of the solute" /"Volume of the solution" ×100`
= `3.5/15 × 100`
Volume percentage = 23.33 %.
