What mass of iodine would react with 48 grams of magnesium to make magnesium iodide?

  1. DrBob222

    Mg + I2 ==> MgI2
    mols Mg = grams/molar mass
    Using the coefficients in the balanced equation, convert mols Mg to mols I2. that's a 1:1 reaction.
    Now convert mols Mg to grams. g = mols MgI2 x molar mass MgI2.
