Use the References to access important values if needed for this question.
A sample of helium gas occupies a volume of 9.44 L at 65.0°C and 394 tor.
If the volume of the gas sample is decreased to 7.97 L, while its temperature is increased to 135.0°C, the resulting gas pressure will be
torr.
Expert Solution
Step 1
Ideal gas equation is represented as follows:
PV = nRT
P = pressure of the gas
V = volume of the gas
n = no. of moles
R = gas constant
T = temperature of the gas
Step 2
Given information:
Pressure of He gas(P1) = 394 torr
Volume of He gas (V1) = 9.44 L
Temperature of He gas (T1) = 65.00C or 338K
Decreased Volume (V2) = 7.97 L
Increased Temperature (T2) = 135.00C or 408 K
