Answer:
The answer to your question is 242 ml
Explanation:
Data
HI 0.211 M Volume = x
KMnO₄ 0.354 M Volume = 24 ml
Balanced Chemical reaction
12HI + 2KMnO₄ + 2H₂SO₄ → 6I₂ + Mn₂SO₄ + K₂SO₄ + 8H₂O
Process
1.- Calculate the moles of KMnO₄ 0.354 M in 24 ml
Molarity = moles / volume (L)
moles = Molarity x volume (L)
moles = 0.354 x 0.024
moles = 0.0085
2.- From the balanced chemical reaction we know that HI and KMnO₄ react in the proportion 12 to 2. Then,
12 moles of HI --------------- 2 moles of KMnO₄
x --------------- 0.0085 moles of KMnO₄
x = (0.0085 x 12)/2
x = 0.051 moles of HI
3.- Calculate the milliliters of HI 0.211 M
Molarity = moles/volume
Volume = moles/molarity
Volume = 0.051/0.211
Volume = 0.242 L or Volume = 242 ml

Answer:
67.4 mol of O atoms
Explanation:
Cassitrerite is a Tin Mineral having a chemical formula SnO₂. As seen in chemical formula there are two moles of Oxygen atoms for each Tin atom. So we can conclude that,
For,
1 mole of Sn in SnO₂ there are = 2 moles of O atoms
So for,
33.7 moles of Sn there will be = X moles of O atoms
Solving for X,
X = (33.7 mol of Sn × 2 mol of O) ÷ 1 mol of Sn
X = 67.4 mol of O atoms
