Question

Ethanol, C2H5OH, burns with the oxygen in air to give carbon dioxide and water.

C2H5OH(l) + 3 O2(g) → 2 CO2(g) + 3 H2O(l)

What is the amount (in moles) of water produced from 0.54 mol C2H5OH?

Answer 1

1 mole C2H5OH(l) + 3 O2(g) → 2 CO2(g) + 3 moles H2O(l)

What is the amount (in moles) of water produced from 0.54 mol C2H5OH

0.54 moles C2H5OH @ 3 moles H2O / 1 Mole C2H5OH = 1.62 moles

your answer is (2 sigfigs) : 1.6 moles H2O
