sample of 0.720 g contains only NaHCO3 and Na2CO3. A student took 0.360 g of the sample and let it fully reacted with 0.100M HCl solution. The student used 50mLof HCl to reach the end point in the reaction. How many millimole of Na2CO3 in the 0.360g of sample? What is the mass percent of Na2CO3 in this sample?
