CaCO3 + 2HCl → CaCl2 + CO2 + H2O
Mm CaCO3 = 100 g/mol
HCl = 35.5 g/mol
1. calcular g de HCl
g HCl = 200 g CaCO3 x 1 mol CaCO3 x 2 mol HCl x 36.5 g HCl
```````````````````` ``````````````` `````````````````
100 g CaCO3 1 mol CaCO3 1 mol HCl
g HCl = 146
2. calcular moles de HCl
n = masa/Mm
n = 146 g / 36.5 g/mol
n = 4 moles HCl
3. calcular volumen de la solución
M = n/V
V = 4 moles / 4 mol/L
V = 1 L de solución.
4. calcular moles de CO2
n = 200 g CaCO3 x 1 mol CaCO3 x 1 mol CO2
