Question

How many moles of water are produced from 32 grams of methane?

Answer 1

Answer:

4 moles

Explanation:

$n_{CH4}$ = $\frac{32}{16}$ = 2 (moles)

CH4 + 2O2 → CO2 + 2H2O

  1     :    2    :     1    :      2

  2                                         (moles)

⇒ $n_{H2O}$ = 2 × 2 ÷ 1 = 4 (moles)
