please help! for B, it should be 305 C inear interpolation) and C should be 533 kg. please show how to get those!

a. Steam calculations again!. A tank whose volume 12 mcontains 6.2 kg of water at 1.4 bar. vapor mixture)? b. What is the temperature? c. We add more steam to the tank while maintain its temperature constant at the value calculated in part b. As a result, the pressure in the tank increases. Determine how much water (in kg) of steam must be added to bring the steam in the tank to the point of condensation. d. Draw a qualitative PV graph and show the path of the process for part c. a.
