Question

When 50 ml of ethanol and 50 ml of water are mixed, predict whether the volume of the solution is equal to, greater than or less than 100 ml. Justify?

Answer 1

Answer:

If you mix 50 ml of water with 50 ml of ethanol, the total volume actual equals less than 100 ml. The reason the mixture does not add up to 100 ml is because the molecules that make up ethanol are smaller than the molecules that make up water. So, the ethanol molecules cram themselves between the water molecules
