The combustion of a sample of butane, C4H10 (lighter fluid), produced 2.46 grams of water. then how much oxygen was used up in moles?

Question

anonymous · Answer

Perhaps you could start by writing an equation for the complete combustion of butane. Then, find the number of moles of water produced to determine the number of moles of hydrogen consumed. See if this gives you the start you need.

The combustion of a sample of butane, C4H10 (lighter fluid), produced 210.46 grams of water.im trying to find the molar mass of water in this equation: 2C4H10+13O2---->8CO2+10H2O

like do i have to multiply 210.26g of h2o by 1 mole of h2o or by 10 moles of h2o as it says in the equation
