## Which of the following is constant for 1 mole of an ideal gas?

One mole of an ideal gas will occupy a volume of **22.4 liters** at STP (Standard Temperature and Pressure, 0°C and one atmosphere pressure).

## What is constant in an ideal gas?

The factor “R” in the ideal gas law equation is known as the “gas constant”. **The pressure times the volume of a gas divided by the number of moles and temperature of the gas is always equal to a constant number**. The numerical value of the constant depends on which units the pressure volume and temperature are in.

## Which statements are correct about 1 mole of ideal gases?

The volume occupied by 1 mole of ideal gas at NTP is **22.4 litre**.

## Does 1 mole of gas always occupy 22.4 liters?

At Standard Temperature and Pressure (STP), 1 mole of **any gas will occupy a volume of 22.4 L**. The Ideal Gas Law, along with a balanced chemical equation, can be used to solve for the amount, either in volume or mass, of gas consumed or produced in a chemical reaction.

## Why does 1 mole of any gas occupy the same volume?

So the volumes have equal moles of separate particles (molecules or individual atoms) in them. Therefore one mole of any gas (formula mass in g), at **the same temperature and pressure** occupies the same volume .

## How is the gas constant defined?

: a general constant in the equation of state **of gases that is equal in the case of an ideal gas to the product of the pressure and volume of one mole divided by the absolute temperature** — see gas law sense c.

## Which is the constant quantity in ideal gas equation?

The proportionality constant, R, is called the gas constant and has the value **0.08206 (L•atm)/(K•mol), 8.3145 J/(K•mol)**, or 1.9872 cal/(K•mol), depending on the units used.
