Consider the reaction MnO2+4HCL===>MnCl2+Cl2+2H2O
How many grams of MnO2 are required to produce 5.6 of Cl2 at stp?MnO2=87

  • Chemistry -

    5.6 what? L?
    You have the balanced equation.
    Convert 5.6 L to mols at STP.
    Use the coefficients to convert mols Cl2 to mols MnO2.
    Then g MnO2 = mols x molar mass.
