Description : A sample of NO experiences a change in pressure from 0.5734 atm to 5.1663 atm. If its new volume is 89.811 L, what was its original volume in liters ____ L?

Last Answer : 809.2(Explanation): boyle's law of PV=PV for this problem. Plug in values we know, (the pressures and new volume) to get 0.5734V=(5.1663)(89.811). Now solve for V by dividing by 0.5734 on both sides. You get 809.1917846. Round to 4 sig figs to get 809.2.
