Ideal gas: Temperture at 1 atm

[Baronen]

Summary: U=3/2*n*R*T

Can some of you help me with this

The total internal energy of an ideal gas is 3770 J. If there are 3 moles of the gas at 1 atm, what is the temperature of the gas?

I use U=3/2*n*R*T but get the wrong answer, (101 K) but it should be 303 K

Hi Baronen
The only thing I can think of is with this line.
The total internal energy of an ideal gas is 3770 J

Does it say 3770J,
or
3770 J/mole
Otherwise I get the same answer as you.

Hey 256Bits

Thanks for the reply.

The question is formed as stated above.
But if you look at it, would a idealgas be 101 K at 1 atm if you have 3 moles of it (that is very cold).
