The heated soup moves to the tip by convection
Answer:
Explanation:
Given the details, we can say that
Pure methanol is a volatile solvent as the vapour pressure has a high value. This means that methanol - methanol intermolecular forces are weak in comparisson to water - water forces. When having about 30% of water in a methanol mixture, the mixture Pv decreased, showing that it is not a volatile mixture, so then there are strong intermolecular interactions between methanol - water, part of it due to the hydrogen bonds.
Molarity = moles/litre
mol/L=g/(g/mol) (which is g times mols per g)
will give you mols then divide that by L to get mol/L
so
M=g x mol/g x L
M=(20 x 1 x 1.50)/39.997
