First, convert grams of the elements to moles. Then you divide by the smallest number of moles to get the lowest whole number ratio.
86g C×1 mol C/12g C = 7.2 mol C/7.2= 1
14 g H×1 mol H/1g H = 14 mol H/7.2= 2
So the empirical formula is C1H2

A major component of gasoline is octane. When liquid octane is burned in air it reacts with oxygen gas to produce carbon dioxide
irakobra [83]

Answer:

0.267 mol

Explanation:

The <em>unbalanced equation</em> for the reaction that takes place is:

  • C₈H₁₈ + O₂ → H₂O + CO₂

Once we balance it we're left with:

  • 2C₈H₁₈ + 25O₂ → 18H₂O + 16CO₂

Using the <em>stoichiometric ratio </em>of water and octane from the balanced reaction, we can <u>convert mol of water into mol of octane</u>:

  • 2.40 mol H₂O * \frac{2molC_8H_{18}}{18molH_2O} = 0.267 mol C₈H₁₈

Thus 0.267 moles of octane are needed to produce 2.40 mol of water.
