Calculating the Volume of a Mixture of Ethanol and Water
2014年11月17日 · So we did a lab where we mixed 10 ml of 95%ethanol with 10 ml of water and the volume of the mixture we measured was 19.60 ml. Even though we know the volume of the mixture is 19.60 our teacher wants us to calculate what the volume of the mixture should have really been and compare it to what we...
How Much Ethanol Can Be Added to a Pressurized Tank? - Physics …
2008年11月15日 · A moonshiner produces pure ethanol (ethyl alcohol) late at night and stores it in a stainless steel tank in the form of a cylinder 0.290 m in diameter with a tight-fitting piston at the top.
