Answer:


\large \boxed{\text{110 mmHg}}}

Step-by-step explanation:

We can use Dalton's Law of Partial Pressures:

Each gas in a mixture of gases exerts its pressure separately from the other gases.

In other words, if a gas makes up 3.0 % of the atmosphere, its partial pressure is 3.0 % of the total pressure.


p_{\text{N}_(2)} = p_{\text{tot}} * \frac{\text{3.0 parts N}_(2)}{\text{100 parts atmosphere}}= \text{3700 mmHg} * \frac{\text{3.0 mmHg}}{\text{100 mmHg}} = \textbf{110 mmHg}\\\\p_{\text{N}_(2)} = \large \boxed{\textbf{110 mmHg}}
