Question

When 2 moles of C6H6 react with excess Oxygen gas, how many moles of water are produced?

C6H6 + 9 O2 ------> 6CO2 + 6 H20

Answer 1

12 moles H₂O

Step-by-step explanation:

To find the amount of water produced, you need to use the given amount and multiply it by the mole-to-mole ratio from the equation. These numbers are the coefficients of the molecules you are converting from and to. When writing the ratio, make sure to arrange it in a way that allows for the cancellation of units.

1 C₆H₆ + 9 O₂ ----> 6 CO₂ + 6 H₂O

2 moles C₆H₆ 6 moles H₂O
--------------------- x ------------------------- = 12 moles H₂O
1 mole C₆H₆
