At 20 degrees C ethanol has a density of 0.789 g/ml and H2O has a density of 1.0 g/ml. What is the % by volume of ethanol of a solution made by adding 50g of ethanol with 50g of H2O? Tutor Answer: Use density = mass x volume to convert 50 g ethanol to volume and to convert 50....
i thought that density = m/v? i've done the math and i think you are right because based on the above formula my answer is 126.74% However, i don't understand why if the density formula is as you stated? 1/50 = .02, 1/.789 = .01578 (0.01578/0.02) x 100 = 78.9%
