C2h4 + O2 - CO2 + H2O
If we start with 20 grams of CH4, how many moles of CO2 will form?

1.428mol of CO2

Explanation:

C2H4 + 3O2 —> 2CO2 + 2H2O

First let us calculate the number of mole present in 20g of C2H4. This is illustrated below:

Molar Mass of C2H4 = (12x2) +(1x4) = 24 + 4 = 28g/mol

Mass of C2H4 = 20g

Number of mole of C2H4 = Mass /Molar Mass

Number of mole of C2H4 = 20/28 = 0.714mol

From the balanced equation,

1mole of C2H4 produced 2moles of CO2.

Therefore, 0.714mol of C2H4 will produce = 0.714 x 2 = 1.428mol of CO2
