1. A military base is contaminated with a plume of dinitrophenyl acetate (DNPA) that has leaked from an underground storage tank. In order to understand the degradation potential, a colleague of

yours measured the change in DNPA concentration over time in pH 5.0 and pH 8.5 solutions at 22.5 °C and for a temperature range of 17.7 to 30 °C (only for pH 5.0 solution, shown next to part d). (a) Determine the molecular formula and calculate the molecular weight of DNPA. Show ALL of your work for full credit.
