A 1.8M HCl solution was standardized against 1.4g sodium carbonate Na2CO3 (MW = 106g/mol) . The Na2CO3 standard required 13.5 mL of the HCl solution to completely react up to the indicator endpoint. Two chemists prepared their samples by taking 12.0-mL aliquots of each household ammonia solution and diluting it to 25.0 mL. With the same titrant and indicator, Chemist #1’s ammonia solution required 15 mL of the standardized titrant, whereas, Chemist #2's ammonia solution required 35 mL of the same titrant. Write the balanced equation for the analyte and the titrant Solve for the exact concentration of the HCl titrant in molarity.
