Question

How many moles of C3H8 will be produced from 75 moles of CO2?C3H8 + 5 O2 → 3 CO2 + 4 H2O

Answer 1

25 moles of C3H8 will be produced from 75 moles of CO2.

Mole calculation

To find the value of moles of a product from the number of moles of a reactant, it is necessary to observe the stoichiometric ratio between them:

                             $C_3H_8 + 5 O_2 = > 3 CO_2 + 4 H_2O$

Analyzing the reaction, it is possible to see that the stoichiometric ratio is 1:3, so we can perform the following expression:

                           

                            C3H8                CO2

                                      $\frac{1mol}{xmol} =\frac{3mol}{75mol}$

                                         $x = 25mol$

So, 25 moles of C3H8 will be produced from 75 moles of CO2.
