Describe the procedure to calculate the density of air.
Procedure to calculate the density of air:
Measure the mass of the empty balloon.
a) Calculate mass of air in the inflated balloon in kg.
b) Calculate the volume of the inflated balloon in m3.
c) Calculate the density of air in kg m-3.
The procedure to calculate air density given the temperature, dew point and
pressure or temperature, pressure and relative humidity.
The density of dry air can be calculated using the ideal gas law,
