The property data that you use is significantly different than given in tables in Borgnakke and Sonntag' Fundamentals of Thermodynamics. Please check it out!
The data from the same table in different textbooks can vary - the main thing is that you use the same table while performing your calculations. The final answer should not change though as we are most often calculating differences while using the tables.
+Ruhul Amin The problem states your 2nd state is completely saturated vapor. Which means your are on that curve line of the dome on the far right. That is a 100% vapor state. Hence, x=100/100 = 1.0 which is the quality. The left curve line of the dome represents 0 quality whereas the far right curve line of the dome represent 1 quality, meaning 0% vapor and 100% vapor respectively.

hi at 2:45 how do we know x2=1.0?
Is this a general rule from the text book?
p.s i am using Borganakke, Sontag Fundamentals of thermo 8e

+Ruhul Amin Maybe it is too late to answer but: it's given that in state 2 there will be only vapor. So, x=1 when we have saturated vapor.
