methanol burns according to the following equation 2CH3OH+3O2---2CO2+4H2O If 4.50 moles of methanol are burnt in oxygen than how many moles of water are produced

Correct answer: C. 9 moles

  • A. 4.5 moles
  • B. 2.25 moles
  • C. 9 moles
  • D. 6 moles

Explanation

2CH3OH => 4H2O 4.5CH3OH => xH2O x= 9moles

About Fundamental Concepts of Chemistry

Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
