a) MM(H₂SO₄): 2*1 + 32 + 4*16= 98 u==> M= 98 g/mol
b) MM[Ca(OH)₂]: 40 + 2*16 * 2*1= 74 u==> M= 74 g/mol
c) MM[Ca₃(PO₄)₂]: 3*40 + 2*31 * 8*16= 310 u==> M=310 g/mol
d) MM(C₂H₅OH): 2*12 + 5*1 + 16 + 1= 46 u==> M= 46 g/mol
e) MM[K₄Fe(CN)₆]: 4*39 + 56 + 6*12 + 6*14= 368 u==> M=368 g/mol
f) MM(BaCl₂⋅ 2 H₂O): 11 + 35,5*2 + 4*1 + 2*16= 118 u==> M= 118 g/mol
