Calculate the amount of grams of carbon dioxide formed from 100 g of octane. The molar mass of octane is 114.33 g/mole. The molar mass of carbon dioxide is 44.0095 g/mole/

2 C8H18 + 25 O2 ---> 16 CO2 + 18 H20

How do I go about doing this problem? How much would the approach change if I had to find the moles of carbon dioxide formed from the same amount of octane? Thanks for any insight into this problem!

• Chem -

each mole of octane produces 8 moles CO2

so, you have 100/114.33 * 8 moles CO2 * 44g/mole

• Chem -

It's like 6.0
