During a chemistry lab, one lab group decomposes potassium chlorate to collect oxygen gas by water displacement. The total volume is 220 milliliters and is collected at a pressure of 101 kPa at 24°C. The vapor pressure of water at 24°C is found to be 2.98 kPa.

What is the pressure of the oxygen collected?

A. 104.28 kPa
B. 101.20 kPa
C. 98.2 kPa
D. 98.02 kPa

Answer :

According to Dalton's law of partial pressure, the pressure of the oxygen collected is 98.02 kPa.

What is pressure?

Pressure is defined as the force applied on an object perpendicular to it's surface per unit area over which it is distributed.Gauge pressure is a pressure which is related with the ambient pressure.

There are various units by which pressure is expressed most of which are derived units which are obtained from unit of force divided by unit of area . The SI unit of pressure is pascal .

In this case, pressure of the oxygen collected is obtained by Dalton's law of partial pressure, as 101-2.98=98.02 kPa.

Thus, the pressure of the oxygen collected is 98.02 kPa.
