Question

The volume of one mole of krypton at STP is?

1) 12.4 liters
2) 22.4 liters
3) 12.4 gallons
4) 6.02 × 10²³ liters

Answer 1

The volume of one mole of krypton at STP is 22.4 liters, as this is the molar volume for any gas under those conditions. Option 2

Step-by-step explanation:

The volume of one mole of krypton gas at Standard Temperature and Pressure (STP) can be determined by using the ideal gas law, which states that this volume is independent of the gas's chemical identity. At STP, which is defined as a temperature of 273 K (0°C) and a pressure of 1 atm, the molar volume of any gas is 22.4 liters. Therefore, the correct answer is:

1 mole of krypton at STP occupies 22.4 liters. Option 2
