195 g of water containing magnesium chloride boils at 102.5 celcuis. what mass of salt is needed?

  • Chemisty -

    Let me check you work on this. The bp elevation is 2.5C

  • Chemisty -

    the answer is 30.1 grams magnesuim chloride but i don't kknow how to get to the answer

  • Chemisty -


    now m=moles/kgwater=moles/.195


    check all that math.
