Good morning, I am looking for help in figuring out how to solve this problem, knowing that the magnetic field was just calculated to be 9.39 tesla. Is there a specific formula and is there any information I'm missing to be able to solve this question?

What is the resonant frequency of the 31P atom in this magnetic field (9.39tesla)?

For a 1 tesla field the Larmor frequency is freq = 28.025 GHz.
