C2H4+3 O2->2 co2+2 H2O
If you start wit 45 grams of C2H4 how many grams of carbon dioxide will be produced?

  • chemistry- stoichiometry problems -

    C2H4 + 302 --> 2CO2 + 2H2O
    1 : 2 mole ratio
    m= 45g m= ?
    M= 28.0 g/mol M= 44.0 g/mol
    n= 45g/28.0 n= 2(1.61mol)
    = 1.61 mol = 3.22 mol
    m= (3.22 mol)
    x (44.0 g/mol)
    = 141.68 g

    Therefore, 141.68 g of carbon dioxide with be produced.
