Question

Calcule as massas de a)AL2(CuO4)3 b)Mg(OH)2 c)Na2SO4 d)C5H8O2

Answer 1

a) Al2(CuO4)3 = 27 x 2 + 63,5 x 3 + 16 x 12 = 436,5 g/mol

b) Mg(OH)2 = 24 + 16 x 2 + 1 x 2 = 58 g/mol

c) Na2SO4 = 23 x 2 + 32 + 16 x 4 = 142 g/mol

d) C5H8O2 = 12 x 5 + 1 x 8 + 16 x 2 = 100 g/mol

espero ter ajudado!.
