A0.110 mol sample of an ideal gas occupies 3.50l. what is the volume of 0 .250 moles of this gas at the same temperature and pressure?

1. A gas at a pressure of 0.925atm occupies a volume of 12.0mL, if it is expanded at constant temperature to 210mL, what is the new pressure? P 2 = P 1 V 1 = 0.925 atm(0.0120L) = 0.0529 atm V 2 .210L 2. A gas at a pressure of 735.2 mm. Hg. occupies a volume of 120.0mL. If the pressure is reduced to 610.0 mm. Hg at constant temperature, what is the new volume? V 2 = P 1 V 1 = 735.2mm(0.1200L) = 0.1446 L P 2 610.0mm 3. An ideal gas with a temperature of 25.0  C occupies 11.0L. What is the new temperature if the gas is cooled enough to occupy 6.00L at constant pressure? V 1 = V 2 ; T 2 = V 2 T 1 = 6.00L(298.15K) = 163K = -111. °C T 1 T 2 V 1 11.0L 4. An ideal gas occupying 4.0L is at a temperature of 20.0°C. What is the new volume if the gas is cooled to –4.0  C? V 2 = V 1 T 2 = 4.0L(269.2K) = 3.7 L T 1 293.2K 5. An ideal gas at STP (273.15K and 1 atm) occupies 3.00L. What is the volume if the gas is brought to 300.0K and 1.30 atm.? P 1 V 1 = P 2 V 2 ; V 2 = P 1 V 1 T 2 = 1atm(3.00L)300.0K = 2.53L T 1 T 2 T 1 P 2 273.15K(1.30atm) 6. A 0.110 mol sample of an ideal gas occupies 3.50L. What is the volume of 0 .250 moles of this gas at the same temperature and pressure? V 1 = V 2 ; V 2 = V 1 n
