## Best answer

Molar gas constant also known as gas constant, the universal gas constant, or the ideal gas constant is afundamental physical constant that arises in the formulation of general gas laws. The molar gas constant is denoted by the symbol R. It is equivalent to the Boltzmann Constant.

### What is gas constant (universal molar gas constant)?

What is gas constant (universal molar gas constant)? – Definition from WhatIs.com The gas constant, also known as the universal molar gas constant, is a physical constant that appears in an equation defining the behavior of a gas under theoretically ideal conditions. The gas constant is, by convention, symbolized R.

### What is the molar volume of an ideal gas?

Vm is the molar volume The specific gas constant The gas constant of a specific gas, as differentiated from the above universal molar gas constant which applies for any ideal gas, is designated by the symbol Rs and is equal to the molar gas constant divided by the molecular mass (M) of the gas: Rs = R M

### What is the gas constant of a specific gas?

The gas constant of a specific gas, as differentiated from the above universal molar gas constant which applies for any ideal gas, is designated by the symbol Rs and is equal to the molar gas constant divided by the molecular mass ( M) of the gas:

### Why is the gas constant expressed in joules per mole per kelvin?

Hence the expression of gas constant in Joules per mole per Kelvin is justified. The Specific Gas Constant of a particular gas or a mixture of gases is calculated by dividing the molar gas constant by the molar mass of the gas or the mixture. The application of specific gas constants is in the field of engineering especially.
