if you have 3 mol CH4, how many grams CO do you form .... CH4+O2--_CO+_H2O?

Question

if you have 3 mol CH4, how many grams CO do you form .... CH4+O2--_CO+_H2O

Answer 1

*The guy below me has it wrong. So does everyone else. Trust my answer. Stoichiometry is my specialty.

Here's the balanced equation:

2CH4 + 3O2 ----> 2CO + 4H2O

3 mol CH4 * (2 mol CO/2 mol CH4) = 3 mol CO

3 mol CO * (28.01 g CO/1 mol CO) = 84.03 g CO

Answer 2

You first have to have a balanced equation

2CH4 + 3O2 == 2CO + 4H2O

If you have 3 moles of CH4,you must multiply by the molar ratio (2/3) to get moles of CO.

Then multiply by the molecular mass and you have your answer

Answer 3

balance the problem: 2CH4+302=2CO+4H20

2CH4+302=2CO+4H20
3MOLE OF CH4

3mole of CH4 * (2mole of CO/1mole of CH4) * (28.01g ofCO/1 mole of C0) = 168.06 g of Co

28.01 g is molar mass of Co
