1) MM(Ni) = 59u
MM{(OH)2} = 2*16 + 2*1 = 34u

MM{Ni(OH)2} = 59 + 34 = 93u

2) MM{(NH4)3} = 3*14 + (4*1)*3 = 54u

MM(Fe) = 56u
MM{(CN)6} = 6*12 + 6*14 = 156u

MM{Fe(CN)6} = 56 + 156 = 212u

3) MM(Bi) = 209u
MM{(SO3)3} = 3*32 + (3*16)*3 = 240u

MM{Bi(SO3)3} = 209 + 240 = 449u

4) MM(Fe4) = 224u
MM{(P2O7)3} = (2*31)*3 + (7*16)*3 = 522u

MM{Fe4(P2O7)3} = 224 + 522 = 746u

5) MM(Al2) = 2*27 = 54u
MM{(C2O4)3} = (2*12)*3 + (4*16)*3 = 264u

MM{Al2(C2O4)3} = 54 + 264 = 318u
