Complete the following table. (Enter all mass and volume data to the closest 0.01 unit. Enter the concentration of NaOH to 3 significant figures.)

i’ve got the data down for table one but had no idea how to solve table two, please help

Part A: Titration of vinegar HC2H302(aq) + OH-(aq) → C2H302 (aq) + H20(1) Complete the following table. (Enter all mass and volume data to the closest 0.01 unit. Enter the concentration of NaOH to 3 significant figures.) Data Table A1: Experimental data mass of beaker volume of vinegar mass of beaker + vinegar mass of vinegar Trial 1 49 95.64 4.0 7.10 49) 102.70 49 7.06 Trial 2 g 49) 116.26 ML 4.9 7.00 9 49) 123.07 g 4.) 6.81 ml concentration of NaOH Initial buret reading 4.9 0.498 490.00 49) 12.60 equivalence point buret reading (titrant volume at which pH changes most rapidly) volume of titrant added equivalent point – Initial buret reading M mL 490.00 mL 40) 10.05 mL 4.9) 10.05 mL mL mL) 49) 12.60 Complete the following table.
