Consider the unbalanced equation: Na+Cl2 = NaCl. What mass of NaCl can be produced from 25.0 grams of Chlorine?

  • chemistry -

    1. Balance the equation.
    2. Convert 25.0 g Cl2 to moles. moles = gram/molar mass.
    3. Using the coefficients in the balanced equation, convert moles Cl2 to moles NaCl.
    4. Now convert moles NaCl to grams NaCl. Grams NaCl = moles NaCl x molar mass NaCl.
    Post your work if you get stuck.

    FIRST, blance the equation.
    2Na + CL2 -> 2NaCl

    SECOND, get the g ( atomic mass. ) for NaCl and Cl.
    NaCL--V
    2Na- 23.00 x 2 = 66.00g
    2CL- 35.45 x 2 = 70.9g

    Add the two together.
    NaCal = 137g

    Cl--V
    2Cl- 35.45 x 2 = 70.9g

    Cl = 70.9G

    LAST,
    Set up your equation, starting with the 25g of Cl you have.

    25gCl2 x 1 molCl2/70.9gCl x 2 mol NaCl/1 mol Cl2 = ( Your answer! )

    Hope I helped. (:

    Add the two together.
    NaCal = 137g
    2 x 23.00 = 46.00, not 66.00
    total 2NaCl should be 117, not 137.
