Question

Химия пожалуйста добрые люди помогите

Answer 1

M (H2SO3) = 1•2 + 32 + 16•3 = 82

M (H2CO3) = 1 •2 + 12 + 16•3 = 62

M ( NaCl) = 14 + 35 = 49

М (Ba(OH)2) = 137 + 16•2 + 2 = 171

M (Ca SO4) = 40 + 32 + 16•4 = 136

M (Ba3(PO4)2) = 137•2 + 31•2 + 16 •4•2= 464

M (KOH) = 39 + 16 + 1 = 56

M (Zn(OH)2) = 65 + 16•2 + 2 = 99

M( K2So4) = 39•2 + 32 + 16•4 = 174

M(CH3COOH) = 12+3+12+16+16+1 = 60

M(ZnSiO3) = 65 + 28 + 16•3 = 141

M (Na2 CO3) = 23•2 + 12 + 16•3 = 106
