The answer is .15 mV. I see you're from New York, NY, which is also where I live. I would love to give you a full explanation to this question and any others you have in a tutoring session. I can also give you deeper explanations than the one I gave above, so you can develop a better understanding. If you're interested, message me and we can set up a session. Thanks!
