Question

Use the following equation to determine how many moles of C are needed to react with 0.500 mole of SO2.

5C + 2SO2 --> CS2 + 4CO

Answer 1

The answer to your question is 1.25 moles of C

Step-by-step explanation:

Reaction

5C + 2SO₂ ⇒ CS₂ + 4CO

Check that the reaction is balanced

Reactant Element Product

5 C 5

2 S 2

4 O 4

Use proportions to find the moles of C needed.

5 moles of C ----------------- 2 moles of SO₂

x moles of C ---------------- 0.500 moles of SO₂

x = (0.500 x 5) / 2

x = 1.25 moles of C
