One mole of any gas at 298 k and 1 atm occupies a volume of 22.4 l. true or false

- False.

Explanations:- One mole of any gas at STP occupies 1 volume of 22.4 L.

STP means standard temperature and pressure. Standard temperature is 273 K and standard pressure is 1 atm.

Here, in the statement the given temperature is 298 K which is not the standard temperature and so the volume of 1 mole of the gas will not be 22.4 L.

The volume could be calculated using ideal gas equation:

PV = nRT

R is the universal gas constant and it's value is .

let's plug in the values and calculate the volume for 1 mole of the gas:

V = 24.5 L

The volume for 1 mol of the gas at 298 K and 1 atm is 24.5 L and hence the statement is false.

a plasma is a warm ionized gasoline consisting of approximately equal numbers of definitely charged ions and negatively charged electrons. the characteristics of plasmas are notably unique from the ones of ordinary neutral gases in order that plasmas are considered a awesome "fourth kingdom of remember."
