Ok, can you see that the moles of ethanol is 1.77/46.086?
What I was actually doing was dividing that fraction by the litres of solution, 0.085. When dividing by a fraction, you multiply by its reciprocal. In other words (1.77/46.086)/(0.085/1) = 1.77/(46.086 * 0.085) I have a tendency to work with fractions and not decimals, as I like to keep my mathematical results as accurate as possible. It's just the way I deal with things, and you'll find that if you express the moles of ethanol as a decimal and divide by the litres, you'll again achieve the same thing
