Hi there, I need help on my homework for chemistry and I do not understand the step on how to work this problem out. Please help me with this problem:

On a Sunday morning while having your breakfast you determine that you need about 2.95X10^(5)J to heat water for your tea in the microwave. If 2.5X10^(24) photons hit the cup every second and you set the timer to 2.4 min, what should the frequency of the microwave be so that the tea is ready in that time?
