23,000. You would just subtract the liabilities.
We are going to use the ideal gas law. First, convert 475 kPa to Pa because the ideal gas law uses SI units. This will be 475,000 Pa.
Rearranging the ideal gas law, we get P1V1/T1 = P2V2/T2. Now plug everything in and solve for P2: (475,000)(4)/(290) = (P2)(6.5)/(277)
I don’t know if this answers your question but here you go:
