A closed vessel contains 0.10.1 mole of a monoatomic ideal gas at 200K200\text{K}. If 0.050.05 mole of the same gas at 400K400K is added to it, the final equilibrium temperature (in K\text{K}) of the gas in the vessel will be close to ______

Correct answer

0

Step-by-step solution

(0.1)(200)+(0.05)(400)=(0.15)T\left(0 .1\right)\left(200\right) + \left(0 .05\right)\left(400\right) = \left(0 .15\right)T

T=20+200.15=8003=266.67T = \dfrac{20 + 20}{0 .15} = \dfrac{800}{3} = 266 .67

=266.67= 266 .67
