Calculate the temperature of 4.0 mol of ...

Calculate the temperature of 4.0 mol of a gas occupying `5dm^3` at 3.32 bar.
`(R=0.083 ba r dm^3 K^-1 mol^-1)`.

A

25K

B

50K

C

75K

D

100K

Text Solution

Verified by Experts

The correct Answer is:
B
T he amount of the gas , n= 4.0mol
Volume of gas y = `5dm^(3)`
Pressure of the gas p = 3.32 bar
R = 0.083 bar `dm ^(3) K ^(-1) mol ^(-1)`
From the ideal gas eqation , we get
`pV = nRT implies T = (pV )/ (nR ) = (0.32 xx 5) (4 xx 0.083 )`
