Result:
Ions interact with hydrogen that has a partially positive charge, facilitating the dissolution of salt in water. On the other hand, sugar is a molecular compound connected by covalent bonds. In a polar covalent bond, the sharing of electrons is uneven

Answer:
- A. Which element, X or Z, has a higher molar mass?
Explanation:
Heating the original compounds intensely to remove all oxygen causes chemical decomposition reactions:
- 2XClO₃ (solid) → 2XCl + 3O₂ (gas)
- 2ZClO₃ (solid) → 2ZCl + 3O₂ (gas)
By measuring the initial mass of each sample and the mass remaining after heating, the student can compute the oxygen gas mass released:
- Mass of oxygen released = initial sample mass minus residue mass
Using this oxygen mass, she can calculate how many moles of oxygen were present in each sample:
- Moles of oxygen = oxygen mass (g) divided by molar mass of oxygen
Next, the moles of the original sample are determined:
- Each mole of XClO₃ or ZClO₃ has 3 moles of oxygen atoms.
So, dividing the moles of oxygen released by 3 gives the moles of the sample.
Applying the formula molar mass = mass / moles, the student finds the molar masses of XClO₃ and ZClO₃.
Thus, this data allows answering question A: Which of X or Z has the higher molar mass?
Given the mass of 
=25.6 g
The molar mass of =390.35g/mol
Conversion of mass of to moles:
Conversion of moles to moles of sulfur:
Conversion of moles of sulfur to individual sulfur atoms using Avogadro's number:
1 mol =
