Question

How many moles of oxygen are required to produce 37.15 g CO2? 37.15 g CO2 = mol O2

Answer 1

I solved the problem and this is correct

Answer 2

0.84 moles of oxygen are required.

Step-by-step explanation:

Given data:

Mass of CO₂ produced = 37.15 g

Number of moles of oxygen = ?

Solution:

Chemical equation:

C + O₂ → CO₂

Number of moles of CO₂:

Number of moles = mass/molar mass

Number of moles = 37.15 g/ 44 g/mol

Number of moles = 0.84 mol

Now we will compare the moles of oxygen and carbon dioxide.

CO₂ : O₂

1 : 1

0.84 : 0.84

0.84 moles of oxygen are required.
