Respuesta :
if you have 150 grams of s8 how many moles of so2 can you make
Answer : You can make 4.68 moles of SO₂
Explanation:
Step 1 : Write balanced equation.
S₈ can combine with oxygen to form SO₂ gas. The balanced equation for this reaction is written below.
[tex] S_{8} + 8 O_{2} \rightarrow 8 SO_{2} [/tex]
Step 2 : Find moles of S₈
The formula to calculate mol is
[tex] mole = \frac{grams}{MolarMass} [/tex]
Molar mass of S₈ is 256.5 g/mol
[tex] mole = \frac{150grams}{256.5 g/mol} [/tex]
[tex] mole = 0.585 mol [/tex]
we have 0.585 mol of S₈
Step 3: Use mole ratio to find moles of SO₂
The mole ratio of S₈ and SO₂ can be found using balanced equation which is 1:8
That means 1 mol of S₈ can form 8 moles of SO₂.
Let us use this as a conversion factor to find moles of SO₂
[tex] 0.585 mol (S_{8}) \times \frac{8 mol (SO_{2})}{1 mol (S_{8})} = 4.68 mol [/tex]
Therefore we have 4.68 moles of SO₂
