Question

determina la composicion sentesimal de Ca(CN)2

Answer 1

Ca(CN)2
Ca: 1 x 40 = 40 g/mol  C: 2 x 12 = 24 g/mol  N: 2 x 14 = 28 g/mol``````````````````````````````````          Mm = 92 g/mol
% Ca92 g ------ 100 %40 g ------     x  x = 43.47 % Ca
% C92 g ------ 100 %24 g ------     x  x = 26.08 % C
% N92 g ------ 100 %28 g ------     x  x =  30.40 % N
