mol = gramos /PM calcular PM CO calcular PM N₂ calcular PM H₂O
gramos =mol .PM C: 12 . 1 = 12 N : 14 . 2 = 28 g/mol H : 1 . 2 = 2
O: 16 . 1 = 16 O : 16 .1 = 16
PM = 28 g/mol PM = 18g/mol
g= mol . PM g = mol. PM g = mol . PM
g = 2,5 mol. 28 g/mol g =0,9mol. 28g/mol g= 1,5mol.18g/mol
g = 70g g = 25,2 g g = 27 g
