How many grams of Co2 are produced from 12 g of CH4 and 133 g of O2
Andru [333]

Answer:

m_{CO_2}=33gCO_2

Explanation:

Hello,

In this case the undergoing chemical reaction is:

CH_4+2O_2\rightarrow CO_2+2H_2O

Next we identify the limiting reactant with the given amounts of methane and oxygen by computing the available moles of methane and the moles of methane consumed by the 133 g of oxygen:

n_{CH_4}^{available}=12g*\frac{1mol}{16g} =0.75molCH_4\\n_{CH_4}^{consumed\ by\ O_2}=133gO_2*\frac{1molO_2}{32gO_2}*\frac{1molCH_4}{2molO_2}=2.08molCH_4

In such a way, the limiting reactant is methane with 0.75 moles which produce the following mass of carbon dioxide:

m_{CO_2}=0.75molCH_4*\frac{1molCO_2}{1molCH_4} *\frac{44gCO_2}{1molCO_2} \\\\m_{CO_2}=33gCO_2

Best regards.
