1.25 moles of CO₂ is formed from 20.0 g of CH4,.
Explanation:
The balanced equation for the combustion of methane produces carbon-di- oxide and water.
CH₄ +20₂ → CO₂ + 2 H₂O
First we need to find the number of moles of methane reacted using the given mass and its molar mass as,
[tex]$ moles of CH_{4} = \frac{mass}{molar mass}[/tex]
[tex]$ moles of methane = \frac{ 20 g}{16 g/ mol} =1.25 moles[/tex]
[tex]$\frac{ 1 mol of CO_{2} }{1 mol of CH_{4} } \times 1.25 mol of CH_{4} = 1.25 mol of CO_{2}[/tex]
Thus it is calculated that 1.25 moles of CO₂ is formed from 20.0 g of CH4,.
