Question

THIS iS A Ratio Problem

Answer 1

Answer:

30 moles of CO₂

Explanation:

balanced equation ,

CS₂+3O₂ → CO₂+2SO₂

From equation, 3 moles of O₂ are needed to make 1 mol of CO₂.

This means to produce 1 mol of CO₂, we need 3 moles of O₂, then how many moles of CO₂ will be produced from 90 moles of O₂ ?

Use unitary method to solve such problems,

Number of moles of CO₂ that will be produced:

= $\frac{90 \times 1}{3}$

=$\frac{90}{3}$

= 30 moles of CO₂
