Masa molowa:

KWASY

H2SO4 = 2 + 32 + 64 = 98 g/mol

HCl = 1 + 35 = 36 g/mol

H4P2O7 = 4 + 62 + 112 = 178 g/mol

H2S2O3 = 2 + 64 + 48 = 114 g/mol

HCN = 1 + 12 + 14 = 27 g/mol

ZASADY

NaOH = 23 + 16 + 1 = 40 g/mol

KOH = 39 + 16 + 1 = 56 g/mol

Ca(OH)2 = 40 + 32 + 2 = 74 g/mol

Mg(OH)2 = 24 + 34 = 58 g/mol

LiOH = 7 + 17 = 24 g/mol

SOLE

NaCl = 23 + 35 = 58 g/mol

K2SO3 = 78 + 32 + 48 = 158 g/mol

Al(NO3)3 = 27 + 14 x 3 + 144 = 213 g/mol

MgSO4 = 24 + 32 + 64 = 120 g/mol

FeS = 56 + 32 = 88 g/mol
