One mole of an ideal gas at STP expands isothermally to a final volume

One mole of an ideal gas at STP expands isothermally to a final volume of 44.83L.Chap 19Calculate delta ?Usys change ?Hsys change ?Ssys change ?Gsys change and ?Asys change for the isothermal expansion done reversibly. I get the Ssys change 5.76 H and U change 0 G=-1572 and A change -1573. Could you check my answers?Calculate delta ?Usys change ?Hsys change ?Ssys change ?Gsys change and ?Asys change for the isothermal expansion done irreversibly at constant pressure (1atm).
