Problem 8.30 - Enhanced - with Feedback 10 of 29 Part A Constants | Periodic Table What is the volume, in liters, at 6 °C, if n and P do not change? Express the volume to two significant figures and include the appropriate units. An air bubble has a volume of 0.520 L at 16 °C. You may want to reference (Pages 268 -269) Section 8.3 while completing this problem. V-Value Units Submit Request Answer PartB What is the volume, in liters, at 428 K, if n and P do not change? Express the volume to two significant figures and include the appropriate units.Explanation / Answer
We have a ideal gas formula,
PV =nRT
Where, P =pressure
V= Volume
n = no. of moles
R= gas constant
T = temperature.
Since , R will always be constant. Moreover,If n and P will also be constant, then the following reduced formula can be used,
V1 T2 = V2 T1
Answer for Part A
V1 T2 = V2 T1
V2 = (0.520 * 279)/ 289 =0.502 L 16oC = (273 + 16)K=289K
Answer for Part B
V2 = (0.520 * 428)/ 289 =0.77 L
Answer for Part C
V2 = (0.520 * 261)/ 289 =0.47 L
Answer for Part D
V2 = (0.520 * 564)/ 289 =1.01 L
