The pressure of gases inside a rigid container is "99000 kPa". The composition of the gases is 68% nitrogen gas, 23% oxygen gas, and 9% neon gas. What is the partial pressure of each gas?

Answer:

See the explanation below.

Explanation:

Multiply the percentage in decimal form of each gas by $\text{99000 kPa}$.

Nitrogen
$0.68 \times 99000 \textcolor{w h i t e}{.} \text{kPa}$$=$$\text{67320 kPa}$

Oxygen
$0.23 \times 99000 \textcolor{w h i t e}{.} \text{kPa}$$=$$\text{22770 kPa}$

Neon
$0.09 \times 99000 \textcolor{w h i t e}{.} \text{kPa}$$=$$\text{8910 kPa}$

The sum of the partial pressures equals the total pressure 99000 kPa.

$\text{67320 kPa" + "22770 kPa" + "8910 kPa"="99000 kPa}$
