Hello I am trying to solve for Tf in the problem below. Ti = 298, Pf = 10, Pi =1

Integration from Ti to Tf of (Cp/T)dt = integration of Pi to Pf dP/P, where Cp = 22.243 + 5.97710^-2*T - 3.499*10^-5*T^2 + 7.464*10^-9*T^3

I am stuck at:

Evalution from 298 to Tf for Ln (Tf/298) - 3.499*10^-5/2*Tf^2 + 7.464*10^(-9)/3*Tf^3 + 5.979*10^-2*Tf = 19.23
