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?
