First you need to know the molecular mass of the compound. The molecular mass is the sum of the atomic masses of each atom in the molecule. This means that you need to count atoms of the same element each time they occur in the compound.
Carbon = 12.0 × 5 atoms = 60.0 grams
Hydrogen = 1.0 × 12 atoms = 12.0 grams
________________________________________
Pentane = 72.0 grams
Now we take the mass in grams and convert it to moles using the formula:
# grams ÷ molecular mass = # moles
220 g ÷ 72.0 g = 3.06 moles pentane

How many moles of co2 will be produced if 5.31 moles of c4h10 are used?
The combustion of butane (C₄H₁₀) can be represented by the balanced equation: 2 C₄H₁₀ + 13 O₂ → 8 CO₂ + 10 H₂O. From this equation, we see that 2 moles of butane produce 8 moles of carbon dioxide. Therefore, if 5.31 moles of C₄H₁₀ are used, the moles of CO₂ produced can be calculated as follows: (5.31 moles C₄H₁₀) × (8 moles CO₂ / 2 moles C₄H₁₀) = 21.24 moles of CO₂.
