Answer:
[tex]U = 1.83 \times 10^5 J[/tex]
Explanation:
Total internal energy of the gas is given by the formula
[tex]U = \frac{f}{2}nRT[/tex]
here as we know that neon gas is monoatomic gas
so we will have
[tex]f = 3[/tex]
n = 50 moles
[tex]T = 20 ^0C = 20 + 273 = 293 K[/tex]
now from above equation we will have
[tex]U = \frac{3}{2}(50)(8.31)(293)[/tex]
[tex]U = 1.83 \times 10^5 J[/tex]
