Question

how many moles of oxygen required for the complete combustion of 2moles
ofC4H6

Answer 1

1 CH4 + 2 O2 -----> 1 CO2 + 2 H2O

Then state the problem

3.0 mol CH4 ------> mol O2?

State the plan:

mol CH4-----> mol O2

Solve:

3.0 mol CH4 x 2mol O2/ 1mol CH4 = 6.0 mol O2 (the 2mol O2 is divided by 1 mol of CH4; these numbers come from the coefficients of the balanced equation.) Notice how the mol of CH4 cancel out so you are left with mol O2. Hope this helps!! please mark as brainlies im trying to level up
