i have used the expression for the buoyant force density*V*g = (mass of air+mass of payload)*g -------> eqn (1) where density*V*g is the the buoyant force i am having trouble relating it to the gas law. I know that density = m/V so PV=nRT can be seen as P = density*R*T / Molar Mass but...

My physics problem is as following, Estimate the average temperature of the air inside a hot air balloon. Assume that the total mass of the unfilled balloon and payload is 500kg. what is the mass of the air inside the balloon? we are told to use a radius of 15m Equations needed density = m/V...
