That's the equation I use use and I get 594 K... I think that's a really high value, is that answer right?

**Chemistry (please help!!)**

Do I not need to turn the temperature to Kelvin for the equation?? If I don't turn it to K I get 49 C... which is a more reasonable value... I left the other values with their same units... please someone answer...
