calculate the numbers of moles of krypton gas contained in a 5.00L container at 6.00 atm and 25.0 C if the gas is argon instead of krypton will the answer change

n of krypton = 1.23 mol.

The no. of moles will not be changed, if the gas is either argon or krypton.

Explanation:

The no. of moles of a gas (n) can be calculated by the general gas law of ideal gases: PV = nRT,

Where, P is the pressure of the gas in atm (P = 6.0 atm).

V is the volume of the gas container in L (V = 5.0 L).

n is the no. of moles of the gas.

R is the general gas constant (R = 0.082 L. atm/mol. K).

T is the temperature of the gas in K (T = 25.0°C + 273 = 298.0 K).

∴ n = PV/RT = (6.0 atm) (5.0 L) / (0.082 L. atm/mol. K) (298.0 K) = 1.228 mol = 1.23 mol.

The no. of moles will not be changed, if the gas is either argon or krypton because it does not depend on the type of the gas.
