Answer :
Final answer:
The partial pressure of krypton in dry air is calculated by multiplying the mole fraction of krypton by the total atmospheric pressure using the given formula. The mole fraction of krypton is 0.00000114 and the total atmospheric pressure is 97.5 kPa.
Explanation:
To find the partial pressure of krypton in dry air near sea level, we must multiply the mole fraction of krypton by the total atmospheric pressure. The mole fraction of krypton in the question is 0.00000114 and the total atmospheric pressure is 97.5 kPa. This is done using the formula: P = (Patm) X (percent content in mixture),
So, we calculate as: Pkrypton = (97.5 kPa) X (0.00000114). On calculating the above expression, we will get the required kPa value for the partial pressure of krypton.
