We know that one mole of any substance contains 6.0225X10^23 particles(atoms, molecules, ions, etc.). Thus 12g of Carbon contains 6.0225X10^23 atoms of Carbon. Therefore 1g Carbon will contain (6.0225X10^23)/12 atoms of Carbon.

Here is the balanced equation: 2C8H18(g)+25O2(g)→16CO2(g)+18H2O(g) number of moles of C8H18 reacted = 6.16×10−2 mol H2O produced = 0.554 mol oxygen is the limiting reactant.

Practically any amount as acetylene gas has a wide range of combustions. However, to burn cleanly, acetylenes formula of c2h2 would weigh 12g/mol carbon 1g/mol hydrogen so (2x12)+(2×1)=26g/2=13g c2h2 so 1/2 mol acetylene to burn most efficiently resulting in co2+h2o would need 3 mol o2. Oxygen is 16g/mol ATOMIC mass.

Answer: 1 mole of anything contains 6.02 x 1023 particles. (Note that "mol" is the abbreviation for mole.) So, 4.21 mol of hydrogen gas contains 4.21 x 6.02 x 1023 = 2.53 x 1024 molecules of hydrogen.

1 mole of carbon-12 has 6.02 x 1023 atoms. Second, you need to know how many moles there are in 20 grams of carbon-12. One mole of anything is the same number of grams as the molecular mass. Since the molecular mass of carbon-12 is 12, there are 12 grams in 1 mole of it, and therefore 20/12 = 5/3 moles in 20 grams.

The molecular masses of hydrogen, oxygen and water are 2 g/mole, 32 g/mole and 18 g/mole respectively. 2×2=4 g of hydrogen reacts with 1×32=32 g of oxygen to form 2×18=36 g of water.
