Question

Calculate the volume of .5 molecsample of gas at 140 k and a pressure of 1.2 atm

Answer 1

582 ml is the volume of gas.

Answer:

Explanation:

Using the ideal law of gases, the kinetic theory of gas can be stated as

PV = nRT

Here P is the pressure and it is given as 1.2 atm, V is the volume, which we need to find. Then R is the gas constant and T is the temperature while n is the concentration present.

As per the give question, P = 1.2 atm, T = 140 K and n = 0.5 moles, R = 8.314

V = $\frac{nRT}{P}$

V = $\frac{(0.5*8.314*140}{1.2}= 582 l.$

So 582 ml is the volume of gas.
