Question

Given the reaction: S + O2 ---> SO2

How many moles of sulfur must be burned to give 0.567 moles of SO2?

Answer 1

The answer to your question is 0.567 moles of S

Step-by-step explanation:

Data

moles of S = ?

moles of SO₂ = 0.567

Balanced chemical reaction

S + O₂ ⇒ SO₂

Reactants Elements Products

1 S 1

2 O 2

Process

1.- Use proportions and cross multiplication to find the moles of Sulfur.

Consider the coefficients of the balanced chemical reaction.

1 mol of Sulfur ------------------- 1 mol of SO₂

x --------------------0.567 moles of SO₂

x = (0.567 x 1) / 1

x = 0.567 moles of S
