Each tablet contains the same number of moles of CaCO3 and MgCO3. One tablet reacted with excess hydrochloric acid to produce 0.24 dm3 of carbon dioxide at r. t.p. CaCO3 + 2HCl → CaCl2 + CO2 + H2O MgCO3 + 2HCl → MgCl2 + CO2 + H2O (i)Calculate how many moles of CaCO3 there are in one tablet. number of moles CO2= number of moles of CaCO3 and MgCO3 = number of moles of CaCO3=​
