Hi , I'd like clear answer, and clear hand write please thanks

Table 4.3 Recommended Trav Spacina Problem No.2 It is desired to absorb 95% of acetone by water from a mixture of acetone and nitrogen containing 1.5mol% of the component in a countercurrent tray tower. Total gas input is 30kmol/h and water enter the tower at a rate of 90kmol/h. The tower operates at 27C and 1atm. The equilibrium relation is Y=2.53X. Determine the number of ideal stages necessary for the separation using: a. Graphical method (plot equilibrium and operating lines in terms of mole ratio Y and X ). b. Kremser analysis method. As A=1, according to Kremser analysis method: N=lnAln[(Y1X0YN+1X0)(1A1)+A1] Where: a= Henry's law constant =2.53
