Calculate the concentration of HCl in the 250.0 mL volumetric flask and calculate the excess number of moles and total number of moles of HCl added to the alkali metal carbonate. From the total number of moles of HCl added and knowing the excess number of moles, calculate the moles of HCl that reacted with M2CO3. Use the following data for the calculations: mass of m2co3 transferred = 0.3877 g volume of 1mol HCl added to alkali metal = 20...
