Question

What mass of carbon dioxide (CO2) is produced when 62.8g of methane (CH4) reacts with oxygen (O2)? Thank you!

Answer 1

172.48g

Step-by-step explanation:

CH4 + 2O2 ---> CO2 + 2H2O

moles of methane = 62.8/16 = 3.92

by stotiometry,

3.92 = n

thus mass of co2 = moles× molar mass = 3.92 × ( 12 + 32)

3.92× 44 = 172.48 grams
