A system consists of an ideal monatomic gas initially at temperature 300.0 K, volume 4.000 L, and pressure 4.000 bar. For the following process, calculate the final values of T, P, V, q, w, ?U, and ?H.
Constant pressure heating to a final temperature of 500.0K, with the gas expanding against an external pressure of 4.000 bar.
From there, how would I find the moles of salicylic acid in aspirin sample (mol) and the mass of salicylic acid in aspirin sample (g), which should help me calculate the percent purity of aspirin and the percent yield of aspirin in sample. Thank y..
