During this experiment, it is necessary to solve for P2 in the Clausius-Clapeyron equation: ln(P2/P1) = ( delta H/R)[(1/T2)-(1/T1)]. Since the right hand side of the equation is able to be determined as a real number (we'll call "z"), the exercise becomes an algebraic problem of this form: ln(a/b) = z Screen reader note: ln left parenthesis a over b right parenthesis = z. End of note Which formula allows for you to solve for the quantity "a"? HINT: See http://www.sosmath.com/algebra/logs/log4/log47/log47.html for a review of solving logarithmic equations.
