What will weigh more a mole of Na or a mole of S?
A mole of S (32 g) weighs more than a mole of Sodium Na (23 g)
Is sucrose more soluble in hot or cold water?
Sucrose is more soluble in hot water due to the increase in molecular motion of the solute and solvent.
Sucrose is soluble in water because the attractive forces between the solute particles are greater than the attractive forces between the solute and the solvent particles.?
You've got it in reverse. When sucrose dissolves in water, sucrose is the solute, and water is the solvent. In order to dissolve, sucrose molecules have to be more attracted to water molecules than they are to other sucrose molecules. If the attraction of sucrose to sucrose was greater than the attraction of sucrose to water, then there would be no reason for the solid sucrose to turn into the aqueous sucrose solution. Sucrose molecules would simply remain firmly attached to each other if that were the case.

Why is it that when you put a potato in a high concentration of sucrose solution does its weight decrease?
This is because the potato, which is mostly water, is in a hypertonic solution (a solution with less water and more solute --here, sucrose-- than the potato). Since the solutions want to reach equilibrium (equal amounts of sucrose and water in both the solution and the potato), water diffuses out of the potato and sucrose diffuses into it. The potato loses its water weight, and sucrose doesn't replace the weight lost, the potato weighs less.
What weighs more one mole of oxygen or one mole of sodium?
One atom of sodium weighs more than one atom of oxygen. Thus, one mole of sodium weighs more than one mole of oxygen.

Which has more mass a mole of potassium or a mole of sodium?
A mole of potassium. Sodium weighs 22.990 g/mol while potassium weighs 39.068 g/mol.
Which weighs more a mole of water or a mole of methane?
It would be a mole of water because you find the molar mass of each compound, finding water is 18.016 g/mol and methane is 16.042 g/mol. Why? water= H2O H 2 x 1.008 O 1 x 16.000 18.016 g/mol methane= CH4 C 1 x 12.010 H 4 x 1.008 16.042 g/mol

What is the stoichiometric relationship between NaOH and HCl?
These chemicals react in a direct proportion of one to one, measured in moles of course, not by weight. A mole of NaOH weighs more than a mole of HCl.
Explain why adding 1 mole of table salt to water raises the boiling point more than adding 1 mole of table sugar to the same amount of water?
Adding one mole of salt raises the boiling point of the water more than adding one mole of sugar to the water
What is the connection between the energy of the water particles at higher temperatures and the resulting solubility of sucrose?
As water temperature increases, the energy of water particles also increases, allowing them to interact more readily with sucrose molecules and increase its solubility. This increased energy helps break down the intermolecular forces holding sucrose together, allowing it to dissolve more easily in the water.
