The molar mass of vanadinite is 1416.27 g/mol. Looking at
the molecular formula we can see that there is 1 mole of Cl for every mole of
vanadinite. Therefore:
mass percent = [(1 mole Cl * 35.45 g/mol) / (1 mole
Pb5(VO4)3Cl * 1416.27 g/mol)] * 100%
<span>mass percent = 2.50%</span>
Chemical Formula of Sodium Sulfate is Na₂SO₄.
As we know, 1 mole of any substance contains 6.022 × 10²³ particles. So, 1 mole of Na₂SO₄ also contains 6.022 × 10²³ formula units of Na₂SO₄.
Also,
1 mole of Na₂SO₄ contains = 6.022 × 10²³ Atoms of S
So,
4.5 moles of Na₂SO₄ will contain = X atoms of S
Solving for X,
X = (4.5 moles × 6.022 × 10²³ Atoms) ÷ 1 mole
X = 2.70 × 10²⁴ Atoms of S
Result:
4.5 Moles of Na₂SO₄ contains 2.70 × 10²⁴ Atoms of Sulfur.
Zinc (ii) sulfate heptahydrate has a formula of ZnSO4.7H2O
Therefore, note that one mole of ZnSO4.7H2O, contains 7 moles of H2O,
Hence, 3.8 moles of ZnSO4.7H2O will contain;
3.8 × 7/1
= 26.6 moles of H2O
