Why is it important that the sample spots are not below the solvent level when the filter paper is first placed in the developing chamber?
By placing the spot above the level of the solvent in the beaker, you slow the flow of solvent which results in improved separation of the components in the spot. If you placed it below the level of the solvent in the beaker, the solvent would just flow at a much faster rate and instead of separating the components in the spot, they would simply be washed away.
Why moles solute before dilution equals moles solute after dilution?
This assumes you are using water (or whatever the original solvent is) to do the dilution so you are not adding more solute, only more solvent,

No, because the solvent must go through the surface to evaporate completely before the paint will be fully cured.
How do you find the solubility of an element?
The solubility is the amount of the solute (substance) in grams per cubic centimeter that can dissolve in a solvent (liquid) before it is saturated. So you would have to measure an amount of the solute before you put it in the solvent, then after the solvent is saturated, measure how much of the solute is left undissolved and subtract that from the original amount. Hope this helps.
