Answer:
1 mole
Explanation:
Given parameters:
Mass of sulfur = 32.066g
Unknown:
Number of moles of sulfur = ?
Solution:
The number of moles of sulfur can be determined using;
Number of moles =
Molar mass of sulfur = 32g/mol
Number of moles =
= 1 mole
Answer:
Van't Hoff factor is 2, in the sodium chloride
Explanation:
Let's raise the dissociations
- Ca₃(PO₄)₂ → 3Ca²⁺ + 2PO₄⁻³
We have 5 moles of ions
We have 4 moles of ions
We have 3 moles of ions
We have 2 moles of ions
