A sample of neon is collected in a 3.25 liter container. The measured pressure is 2.5 atmospheres when the temperature is 10.0 °C. Determine the volume the sample of neon would occupy under the conditions of STP?

Use (P1V1/T1) = (P2V2/T2)

STP is 1 atm for P and 273 K for T. T1 will be 273 + 10 = 283 K
