Explanation / Answer

   1)    a) RbNO2,   b) BCl3 c)AgClO4 d)(NH4)2SO4 e)IF7   f) Potassium dihydrogen ( name isincomplete ) g) CaHPO4   h)Mg3(PO4)2    i)NaHS j) K2S ,   k) CuCN l)SrCl2   m)Sr(ClO2)2   o)Na2(NH4)PO4
p) PbCO3 q)SnF2 r)P4S10 s)HgO t) Hg2I2 u)SeF6 2) 1 amu = 1.6654 x 10-24 g            13.2 amu = 13.2 x 1.6654 x10-24 g                                = 21.98328 x 10-24 g 2) 1 amu = 1.6654 x 10-24 g            13.2 amu = 13.2 x 1.6654 x10-24 g                                = 21.98328 x 10-24 g
