A 1 liter jar contains 0.5 moles of gas at a pressure of 2 atm. What is the temperature of the gas?


What is the volume of a
container of 4 moles of gas at 200 K with a pressure of 3 atm?


Your scientist friend is trying to figure out how many molecules of gas are in a container. They know that the container has a volume of 5 liters, and they measured the pressure and temperature to be 3.5 atm and 275 K. From this information, what do you tell them the mole measurement should be?

Respuesta :

Answer:

See below  ( Ideal gas law)

Explanation:

A)   PV = n RT       P = 2 * 760 = 1520 mm  

    1520 ( 1)  =  .5 (8.314)(T)       T is in Kelvin

     T = 365.64 K

B) PV = nRT

   3 ( 760) V = 4 ( 8.314)(200)

           V = 2.92 Liters

C) PV = nRT

    3.5 (760) (5) = n (8.314)(275)    n = 5.8 moles
