of The total volume required to reach the endpoint of a titration required more than the $50mL$ total volume of the buret. An initial volume of $49\mathrm{.}60+-0\mathrm{.}04mL$ was delivered, the buret was refilled, and an additional $1\mathrm{.}30+-0\mathrm{.}06mL$ was delivered before the endpoint was reached. The titration of a blank solution without the analyte required $0\mathrm{.}41+-0\mathrm{.}04mL.$ Calculate the endpoint volume corrected for the blank and its absolute uncertainty.

Note: Significant figures are graded for this problem. To avoid rounding errors, do not round your answers until the very end of your calculations.
