4. A 35.0 mL sample of 1.00 M KBr and a 60.0-mL sample of 0.600 M KBr are mixed. The solution is then heated to evaporate water until the total volume is 50.0 mL. What is the molarity of the KBr in the final solution?

  • chemistry - ,

    mols KBr soln 1 = M x L = ?
    mols KBr soln 2 = M x L = ?

    final M = total mols KBr/volume in L.
