mol = g
PM despejas gramos y calcular peso molecular de cada compuesto
g = mol .PM
calcular PM CO₂ calcular PM CaCl₂ Calcular PM K
C : 12 . 1 = 12 Ca : 40 . 1 = 40 K = 39 . 1 = 39 g/mol
O : 16 . 2 = 32 Cl : 35,5.2 = 71
PM = 44g/mol PM = 111 g/mol PM = 39 g/mol
g = 0,34 mol . 44 g/mol g = 0,97mol . 111g/mol g = 7,35 mol . 39 g/mol
g = 14,96 g g = 107,67 g g = 286,65 g
