It is found that, when a dilute gas expands quasistatically from 0.40 to 5.0 L, it does 210 J of work. Assuming that the gas tem
fenix001 [56]

Answer:

n=0.033mole

Explanation:

From the question we are told that:

Initial volume V_1=0.40L

Final VolumeV_2=5.0L

Work W=210J

Temperature T=300k

Generally the equation for Ideal gas is mathematically given by

W=nRTIn\frac{V_2}{V_1}

n=\frac{W}{RTIn\frac{V_2}{V_1}}

n=\frac{210}{8.32*300In\frac{5.0}{0.4}}

n=0.033mole
