9.84 * 10^-4
The easiest way I remember is making the decimal first and then seeing what way the 0's are. In this case it is going left so it will be a negative exponent and if you count from 9.84 and move the decimal left 4 that's your answer.
The balanced chemical
reaction will be:
CH4 + 2O2 → CO2 + 2H2O
We are given the amount of carbon dioxide to produce from the reaction.
This will be our starting point.
560 L CH4 ( 1 mol CH4/ 22.4 L CH4 ) (2 mol O2/ 1 mol CH4 ) (
22.4 L O2 / 1 mol <span>O2</span><span>) = 1120 L O2</span>
