The total volume required to reach the endpoint of a titration required more than the 50 ml total volume of the buret. An initial volume of 49. 63 ± 0. 04 ml was delivered, the buret was refilled, and an additional 1. 67 ± 0. 04 ml was delivered before the endpoint was reached. The titration of a blank solution without the analyte required 0. 54 ± 0. 04 ml. Calculate the endpoint volume corrected for the blank and its absolute uncertainty
