DATA AND CALCULATIONS Table1. Preliminary Data Molarity of KOH 1.5 M Molarity of H2SO4 1.5 M Molarity of HNO3 1.5 M Total volume of acid+base 60.0 mL The volumes of acid to base ratio were calculated. For the 80/20 ratio and a total volume of 60.0 mL, Volume of H 2 SO 4 = 0.80 x 60.0 mL =48.0 mL Volume of KOH = 0.20 x 60.0 mL =12.0 mL Table 2. Summary of Calculated Volume Ratios Volume Ratios of Acid/Base Volume ratio Used (mL/mL) H 2 SO 4 /KOH 80/20 48.0/12.0 50/50 30.0/30.0 20/80 12.0/48.0 HNO 3 /KOH 80/20 48.0/12.0 50/50 30.0/30.0 20/80 12.0/48.0 Table 3.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
