please solve by steps and tell me how

Problem 3 ( 4 points) A pellet of Zn of mass 32.7g is dropped into a flask containing ditute H2SO at an external pressure of P an 1 atm \& temperature T=298K. Assume ideal gas in all your work. Data: atomic mass of 7n is 65.4g/mol.w=nRTln(V/V0).R=0.08206atmL/(molK)=8.31J/(molK). (a) Write the balanced reaction ( 1 point)? Note that H2(g) is formed, (b) Calculate the irreversible work (in Joules) for the expansion process ( 1 point). (c) What is the isothermal reversible work (in Joules) of exparsion of n=2 moles of H2 (g) to a volume two times its initial volume at T=298K (1 point)? (d) If the container is closed, what is the work done by H2 (g) (0.5 point)? (e) If H2 (g) expands against vacuum, what is the work done ( 0.5 point)
