The ideal gas equation is PV=nRT where P is pressure, V is volume, n is the number of moles, R is a constant, and T is temperature. You are told that a sample of gas has a pressure of P = 859 torr, a volume of V = 8960 mL, and a temperature of T = 304 K. If you use R = 8.206*10-2 L⋅atm / (K⋅mol), which of the following conversions would be necessary before you could find the number of moles of gas, n, in this sample?

Take a look to R, where the units are L. atm/K. mol ... your pressure is in Torr ... so make the conversion to atm. (760 Torr is 1 atm) and then take the volume ... as you have mL, remember that R is with L, so convert mL to L by making the division / 1000. Pressure and volume are those you have to convert
