how many moles of oxygen are needed to react with 3.5moles of ethylene, considering the combustion of ethylen C2 H4 + 3O2 -- 2CO2 + 2H2 O

how would i solve this question what would be the steps

  • chemistry -

    the equation is balanced. so you do:
    3.5 moles C2H4 * 3 moles O2 / 1 mole C2H4 = 10.5 moles O2

  • chemistry -

    this part means that 3 moles O2 is over 1 mole C2H4 if that wasn't clear.

  • chemistry -

    thank you
