Ok...here's the chemistry problem...please tell me if you think my answer is correct:

If the human body can only withstand 70 bars of pressure and 2.0 atm's of pressure are applied per hour, how many hours will it take for the body to die?

2.0 atm's equal 2.0 bars because so I think the answer is 35 hours.  Do you agree?
