In summary: HeliumSo that means...(930 kg) + (297 kg) + cargo mass = F_boyancyBut what is cargo mass?I don't know how to get it.In summary, the conversation discusses various problems related to fluid mechanics. The first problem involves estimating the mass of a car based on the pressure in its tires and the area of the tires' "footprint." The second problem involves calculating the maximum cargo that a balloon filled with helium can lift, taking into account the weight of the balloon structure and the buoyant force of the helium. The third problem requires identifying the likely identity of a metal based on its mass in air and

Actually you you can just minus the two to get the water displaces and change it into kg = .0081

63.5/.0081 = 7839! :)
