math (steve for your help)

0.224g sample the contained only bacl2 and kbr required 19.7ml of 0.1M agn03 to reach the end point. Calculate the percent of each compound present in the sample.

Steve want you step by step for me.

  2. BaCl2 + 2AgNO3 ==> 2AgCl + Ba(NO3)2 and
    KBr + AgNO3 ==> AgCl + KNO3

    g BaCl2 + g KBr = 0.224g
    2*mols BaCl2 + mols KBr = mols AgNO3
