Answer to Question #266055 in General Chemistry for nadiya

Question

What is the temperature (in K) of 0.715 mole of neon in a 2.00 L vessel at 4.68 atm?

Answer 1

We'll begin by writing out the information provided by the question. This includes:

Number of mole (n) = 0.715 mole

Volume (V) = 2.00 L

Pressure (P) = 4.68 atm

Temperature (T) =?

Recall: that the gas constant = 0.082atm.L/Kmol

With the ideal gas equation PV = nRT, the temperature of the gas can be obtained as follow:

PV = nRT

4.68 x 2 = 0.715 x 0.082 x T

Divide both side 0.715 x 0.082

T = (4.68 x 2) /(0.715 x 0.082)

T = 176.97 K

Now, We can also express the temperature obtained in celsius as shown below:

Temperature (celsius) = temperature (Kelvin) - 273

Temperature (celsius) = 176.97 - 273

Temperature (celsius) = —96.03°C

The temperature of the Neon gas is

—96.03°C
