mass H2O = mass alcohol
Density H2O * Volume H20 = Density alcohol * Volume alcohol
Volume H2O = (Density alcohol * Volume alcohol)/Density H2O
plug in the numbers
Density H2O * Volume H20 = Density alcohol * Volume alcohol
Volume H2O = (Density alcohol * Volume alcohol)/Density H2O
plug in the numbers
