Answer

This equation relates the pressure of a gas with its density, temperature, and molar mass. It is derived from the ideal gas law by manipulating the relationships between these variables.

Step 2

pV = MRT

Answer

This is the classic form of the ideal gas equation, where pressure multiplied by volume equals the product of molar mass, gas constant, and temperature. It is widely used in thermodynamics and gas calculations.

Step 3

pV = \frac{cRT}{M}
