Question #296b3

Answer 1

864 g

Explanation:

The equation is: `C_2H_5OH + 3O_2 -> 2CO_2 + 3H_2O`

So 2 moles of carbon dioxide are produced by 3 moles of oxygen. Therefore, for 18 moles of carbon dioxide, you need (18/2) x 3 = 27 moles.

Molar mass of oxygen gas is 32 g/mol, so you would need 27 x 32 = 864 g of oxygen
