Question: Dry air is 78.1% nitrogen. What is the partial pressure of nitrogen when the atmospheric pressure is 1.01×10⁵ N/m²?

Answer

The partial pressure of nitrogen is $7.89 \times 10^{4} N / m^{2}$

Step 1: Introduction

We apply the formula for partial pressure which is to find partial pressure by multiplying nitrogen percentage by total pressure.

Step 2: Given parameters and formula for partial pressure

Total pressure = Atmospheric pressure = $1.01 \times 10^{5} {N/m}^{2}$

Percentage of nitrogen =78.1%

The formula for partial pressure $P_{partial} = \frac{% Nitrogen}{100} \times P_{total}$

Here, P_partial partial pressure and P_total total pressure.

Step 3: Calculate the partial pressure

The partial pressure of nitrogen in the atmosphere

$P_{partial} = \frac{% N i t r o g e n}{100} \times P_{total} P_{partial} = \frac{78.1 (1.01 \times 10^{5} {N/m}^{2})}{100} \times P_{total} {=7.89×10}^{4} {N/m}^{2}$

Therefore, partial pressure of nitrogen is ${\rm{7}}{\rm{.89 \times 1}}{{\rm{0}}^{\rm{4}}}\;{\rm{N/}}{{\rm{m}}^{\rm{2}}}$
