If I make a solution by adding water to 75mL of ethanol until the total volume of the solution is 375ml, what is the percent by volume of ethanol in the solution?

Answer:

$375 + 75 = 450 \\ 75 \div 450 = 0.1666 \\ 0.1666 \times 100\% = \\ 16.66\%$

or

$75 \div 375 = 0.2 \\ 0.2 \div 75 = 0.2666 \\ 0.2666 \times 100\% = \\ 26.66\%$
