The question asks for energy transfer by mass not seconds, basically specific energy... Shouldn't the answer therefore be in a per kg format?

In the property tables in my textbook (Fundamentals of Thermodynamics, 8th Edition), the h value for saturated R-134a at 140 kPa is ~ 386 kJ/kg. Does it make sense that there is such a huge difference?
