Question

calcular la masa de sulfito férrico y meta carbonato de aluminio

Answer 1

Fe2(SO3)3 = sulfito férrico

Fe: 2 x 56 = 112 g/mol

S:  3 x 32 = 96 g/mol

O: 9 x 16 = 144 g/mol

``````````````````````````````````````````````````````

          Mm  = 352 g/mol

Al2(CO3)3 = meta carbonato de aluminio

Al: 2 x 27 = 54 g/mol

C: 3 x 12 = 36 g/mol

O: 9 x 16 = 144 g/mol

````````````````````````````````````````````````

   Mm = 234 g/mol
