When a 200 g sample of magnesite interacts with an excess of hydrochloric acid, carbon monoxide 4 with a valence volume of 40 liters is released under normal conditions, calculate the mass fraction of magnesium carbonate in magnesite.
find the amount of carbon dioxide
n (CO2) = n (MgCO3) = 1.8 mol
calculate the mass of pure magnesium carbonate
m (MgCO3) = 151.2 g
find the mass fraction of magnesium carbonate in magnesite
w = (151.2 / 200) * 100% = 75.6%
