Basic stoichiometry

  1. Nov 12, 2013 #1
    1. The problem statement, all variables and given/known data

    BaCl2+ 2NaF -->BaF2 + 2NaCl

    2. Relevant equations

    See above...how to get 100g of the BaF2 product?

    3. The attempt at a solution
    Did molecular weight of each compound in moles/g

    Found MW for BaF2 as 173.31
    Then took 100g/173.31 to get 0.57 moles. Did MW for other compounds now not sure where to go from here?

    Have you read the linked page?

    How many moles of BaCl2 needed to produce 0.57 moles of BaF2?

    How many moles of NaF needed to produce 0.57 moles of BaF2?

    Need 1.14moles to produce 0.57 moles BaF2
    Need 0.57 BaCl2 moles to produce 0.57 moles BaF2
    So I need 47.89g of NaF
    And 118.77g of BaCl2
    Is that right?
