PV = nRT
Use the Ideal Gas Law— —to solve the problems below. Remember: “Density = mass/volume” (D = m/V) & “number of moles = mass/molar mass” (n = m/MM) P = pressure, V = volume in liters, n = number of moles of gas particles, T = temperature in Kelvin R = 0.082-(L atm)/(mol K) = 8.31-(L kPa)/(mol K) = 62.4-(L torr)/(mol K) 1…How many moles of oxygen will occupy a volume of 2.5-liters at 1.2-atm and 25oC?
