Homework Statement
A meteorological balloon has volume of 20.0 m3 and a weight of 10.5 kg (gas included).
The density of the air is 1.18 kg/m3 and acceleration of gravity 9.81 m/s2
Homework Equations
What amount of cargo in kg can the balloon lift?
The Attempt at a Solution
Can you please advise about the starting point, it has certainly something to do with the density of air.
I'm using the principle PV=nRT but it's not taking me any further
