please help me with this one

Question 2 (20%): A rigid tank contains 3 kg of liquid-vapor mixture of H20, initially at 130C with a quality of 0.605. Heat transfer to the contents of the tank occurs until the temperature reaches 180C. Determine; (5%) (a) the mass of vapor initially present in the tank, in kg (5%) (b) the final pressure, in kPa (do not interpolate, take the nearest value), (5%) (c) the amount of heat transfered to the system, in kJ, and (5%) (d) show the process in Temperature-specific volume (T-v) diagram in reference to the saturation lines
