Question

composicion porcentual de ch2

Answer 1

  Propanol CH3-CH2-CH2-OH formula Semidesarrollada 
Propanol C3H8O formula Molecular Masa molecular = 60 g 

Composición % = (masa del elemento/masa molecular) * 100 
Composición % (C) = (36 g / 60 g)*100 = 60 % 
Composicion % (H)= (8 g / 60 g)*100 = 13.33 % 
Composicion % (O)= (16 g / 60 g)*100 = 26.66 %
