Question

How many grams of CO are produced when 35.2g of C reacts

Answer 1

6.5 g Fe2O3 x 1 mol Fe2O3/ 159.9 g Fe2O3 x 2 mol Fe/1 mol Fe2O3 x 55.8 g Fe/ 1 mol Fe = 4.5 g Fe <<< Answer

Steps:

1) start with reactant provided in the question.

2) calculate the grams per mole of that reactant.

3) determine the ratio of the given reactant to the (desired) reactant in the question.

4) calculate the grams per mole of the desired reactant.

If everything cancels out, you've set your factors up properly

Answer 2

`m_(CO)=82.13gCO`

Step-by-step explanation:

Hello,

Considering the reaction:

`2C+O_2\rightarrow 2CO`

By means of stoichiometry, the produced grams of CO result:

`m_(CO)=35.2gC*(1molC)/(12gC)*(2molCO)/(2molC)*(28gCO)/(1molCO) \\m_(CO)=82.13gCO`

Best regards.
