Question

How many moles of acetylene does it take to produce 9.60 moles of carbon dioxide?

Answer 1

Given:

moles of acetylene = 9.60 mol

We want to know the moles of CO2 that will be produced from C2H2.

Using the following balanced equation:

`2C_2H_2+5O_2\rightarrow4CO_2+2H_2O\text{ }`

We will use the stoichiometry to solve the problem.

The molar ratio between C2H2 and CO2 is 2:4

Therefore the number of moles of CO2 = 9.60 mol x (4/2) = 19.2 mol

The number of moles of CO2 = 19.2 mol
