Thermodynamics: Property Tables Example

I solve the following problem in this video (From Thermodynamics: An Engineering Approach, cengel 8th Ed. Number 3.29).
A piston-cylinder device contains 0.88-kg of refrigerant-134a at 10 degree C. The piston that is free to move has a mass of 12-kg and a diameter of 25-cm. The local atmospheric pressure is 88-kPa. Now, heat is transferred to the refrigerant-134a until the temperature of the refrigerant is 15 degrees C. Determine (a) the final pressure, (b) the change in volume of the cylinder and (c) the change in enthalpy of the refrigerant-134a.

90.4kPa is 0.0904MPa, not 0.094MPa, at 19:18 The specific volume at 90.4kPa and -10C I got was 0.241762 m^3/kg
