Question

If you have 150 grams of s8, how many moles of so2 can you make?

Answer 1

if you have 150 grams of s8 how many moles of so2 can you make

Answer 2

Answer : You can make 4.68 moles of SO₂

Step-by-step explanation:

Step 1 : Write balanced equation.

S₈ can combine with oxygen to form SO₂ gas. The balanced equation for this reaction is written below.

`S_(8) + 8 O_(2) \rightarrow 8 SO_(2)`

Step 2 : Find moles of S₈

The formula to calculate mol is

`mole = (grams)/(MolarMass)`

Molar mass of S₈ is 256.5 g/mol

`mole = (150grams)/(256.5 g/mol)`

`mole = 0.585 mol`

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

`0.585 mol (S_(8)) * (8 mol (SO_(2)))/(1 mol (S_(8))) = 4.68 mol`

Therefore we have 4.68 moles of SO₂
