Answer:


U = 1.83 * 10^5 J

Step-by-step explanation:

Total internal energy of the gas is given by the formula


U = (f)/(2)nRT

here as we know that neon gas is monoatomic gas

so we will have


f = 3

n = 50 moles


T = 20 ^0C = 20 + 273 = 293 K

now from above equation we will have


U = (3)/(2)(50)(8.31)(293)


U = 1.83 * 10^5 J
