Question

Q.37 If 15g of sulphur are burnt, what volume of SO2 is produced at STP? A. 10.5 1 dm3 B. 30dm? C. 20dm? D. 100dm​

Answer 1

Answer:

Explanation:

S + O2 → SO2

Here 32g sulfur reacts with 32g of oxygen and produces 64g sulfur dioxide.

So 15g of sulfur has 15/32 = 0.46 moles.

So 15g sulfur gives 0.46 moles of sulfur dioxide. The volume of sulfur dioxide will be at STP

0.46 = x / 22.4

X = 0.46 × 22.4

X = 10.304 L at STP.

Hope it helps!
