2c6h14 + 19 o2 --> 12 co2 + 14 h2o

using the above reaction, how many moles of c6h14 are needed to produce 8.86 moles of water

1.27 moles (3 s.f.)

Explanation:

Mole ratio of water: C6H14

= 14:2

= 7:1

This means that to produce 7 moles of water, 1 mole of C6H14 is needed. Or 1/7 mole of C6H14 is needed to produce 1 mole of water. So if you need 8.86 moles of water, 8.86(1/7) moles of C6H14 is needed.

For 8.86mol of water, moles of C6H14 needed

= 8.86/7

= 1.27 moles (3 s.f.)

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made
