How Long to Heat Ammonia Gas by 12°C with Solar Power?

[cash.money]

Homework Statement

The sun heats 2.00 x 10^2 kg of ammonia gas that is kept at constant volume in a large tank. Assuming that solar radiation of 6.00 x 10^2 W caused the heating, determine the length of time it took to raise the ammonia's temperature by 12°C.

You will have to show us what you have done. How many moles of ammonia do you have? What is the molar heat capacity of ammonia gas at constant volume?
