A 2.500 grams sample of a mixture of sodium carbonate (Na2CO3) and sodium chloride (NaCl) is dissolved in 25.00 mL of 0.798 M HCl (hydrochloric acid). Some acid will remain after the treatment of the sample. If 28.7 mL of 0.108 M NaOH is required to titrate the excess HCI then how many moles of sodium carbonate were present in the original sample? Hint: The moles of Na2CO3 present is equal to one- half the number of H30* moles and...
