At 1.70 atm, a sample of gas takes up 4.251. If the pressure in the gas is increased to 2.40 atm, what will the new volume be? m (6) P 1:70 atm = 172252-5 Pa V = 4.25x10 m D 1 atm = 101325 Pa 11 = 0.001m Pa = 2.40 atm = 243180 Pa V = 2 fexced mass of gas at constant Temperature Volume vanes inversely with pressure P V = P V. - Gas Laws State the ideal gas equation (2) PV = nRT = 11 C 13225 2.5x4.25x10 24 31 80 V/ = Pv = P2 Neon. c. A sample of Ne gas occupies 0.220 at 0.86 atm. What will be its volume at 29.4kPa? (4). P = 0.86 atm = 87139.5 Pa D V = 0.2201 = 2:21154 m P = 29.410 Pa V2 = ?
