Estimate the vapor pressure of acetone (mm Hg ) at 50C (a) from data in Perry's Chemical Engl. neers' Handbook and the Clausius-Clapeyron equation, (b) from the Cox chart (Figure 6.1-4), and (c) from the Antoine equation using parameters from Table B.4. (For part a: p=400mmHg at 39.5C,p=760mmHg at 56.5C ) (For part c: use A=7.02447,B=1161,C=224,p in mmHg,T in C )
