Two moles of a hydrocarbon for complete combustion consume 13 moles of oxygen.When 1 mole of it is subjected to complete combustion,the number of moles of water vapour formed is one mole more than the number of moles of Co2 formed. Identify the formula of Hydrocarbon.​

Answer 1

Avogadro's number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro's number. To convert from atoms to moles, divide the atom amount by Avogadro's number (or multiply by its reciprocal)...
