I need help in my lab report for my envirornmental engineering report. the lab consist of the calibration data, and strong and weak acid titration. there an excel work need to be finish first. I already collect the data for each section. so in the excel sheet that attached has three sheets on it: one for the calibration question, second for strong acid titration and the last one for the weak acid titration. I also attached the instruction for the lab assignment. I already start working on the calibration data in the first sheet in the excel sheet . please correct if there any issues with the calculation.
