A barometer is a scientific instrument that is used to measure air pressure in a certain environment.
The molar mass of a chemical compound is defined as the mass of a sample of that compound divided by the amount of substance in that sample.
Value of molar gas constant is 8.314 J / mol·K.
Use Charles law.
Temperature remains constant.
The density of a substance is given by the number of mass of the gas per unit volume.
High pressure and low temperature
