Question

K36 of 50 In the simulation, set the temperature of the sample gas to 304 K. Click on the "Run" button and observe the number of moles of the gas varies with an increase in the gas's volume. Then, click on the "Reset button set the temperature of the sample gas to 504 K, and click on the "Run" button again. Observe the graph produced in the simulation and select the correct options listed below. Check all that apply. View Available Hint(s) The pressure of the sample gas increases with an increase in volume. The volume of the sample gas increases linearly with the number of moles The volume of the gas doubles when the number of moles of tie gas is doubled at the same temperature volume is inversely proportional to the number of moles of the gas. Submit Determining the number of moles from the given volume using Avogadro's law

Explanation / Answer

Part A :

Using the ideal gas law , pV = nRT ,

where p is pressure , V is volume , n is number of moles , R is universal gas constant and T is temperature.

So here , the correct statements are :

The volume of the sample increases linearly with the number of moles

The volume of the gas doubles when the number of moles of the gas is doubled at the same temperature

Part B :

Uisng the ideal gas law , pV = nRT ,

putting all the values we get :

1.0 x V1 = 1.0 x 0.0821 x 273

V1 = 22.4 L

The final volume V2 will be double of V1 , as the numbe rof moles are 2.0 now

So :

V2 = 2.0 x 0.0821 x 273

= 44.8 L
