How many moles of gas are in a container that has a volume of 20.5 mL, temperature of 303 K, and pressure of 1.10 atm? Assume ideal gas behavior. L atm L kPa • Use R-0.08206 mol K vor 8.314 v for the ideal gas constant. mol K • Your answer should have three significant figures.
A fixed amount of ideal gas is held in a sealed container. The initial volume, pressure, and temperature are [recall that 1L = 10−3 m3, and 1atm = 101,300Pa] V = 40 L P = 2.5 atm T = 400 K. (a) Compute the new temperature if the pressure is reduced to P = 1.0atm while the volume is held constant. (b) Compute the new volume if the temperature increases to 600K while the pressure is reduced to 2.0atm. (c)...
A gas is heated from 258 K to 293 K while its volume is increased from 25.0L to 32.5 L by moving a large piston within a cylinder. If the original pressure was 1.18 atm, what would be the final pressure? My No A gas is heated from 258 K to 293 K while its volume is increased from 25.0 L to 32.5 L by moving a large piston within a cylinder. If the original pressure was 1.18 atm, what...
