If a balloon filled with air contains 79.03 kPa nitrogen, 21.27 kPa oxygen and 10.1 kPa of
argon, what is the total pressure of the balloon? Enter the number to the nearest tenth
place.

The total pressure of the ballon will be 110.3 kPa.

Explanation:

As per Dalton's law of partial pressure, the mixture of gas particles having different partial pressures will sum up to give the total pressure of the combined substance.

As here three gas particles are given as nitrogen, oxygen and argon with partial pressure of 79.03 kPa, 21.27 kPa and 10.01 kPa, respectively.

Then, the total pressure will be the sum of all these three partial pressures.

Total pressure = 79.03 + 21.27 + 10.01 = 110.31 kPa.

Thus, the total pressure of the ballon will be 110.3 kPa.
