Answer

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

Step by step solution

Introduction

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

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.

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 ${\rm{7}}{\rm{.89 \times 1}}{{\rm{0}}^{\rm{4}}}\;{\rm{N/}}{{\rm{m}}^{\rm{2}}}$
