I am getting Mass flow rate of -0.22220825 at Outlet and 0.22212315 at Inlet so higher values at the outlet which is not physically possible.

Generally mass flow values at outlet should be closer to inlet values for the simulation to converge

I am currently using pressure inlet and pressure outlet( the condition idicates that the flow becomes 0 at outlet )

Do I then take my mass flow inlet values and run a diff simulation using mass flow inlet values and should i use pressure bc at the outlet ?

That's a difference of 0.01%. Fortunately/unfortunately, you are not doing real world physics but trying to do it numerically on a computer. There is such a thing as numerical errors.
