Answer:

26.2kPa is the partial pressure of nitrogen

Explanation:

<em>Assuming the partial pressure of Carbon dioxide is 0.070atm</em>

<em />

The total pressure of a mixture of 3 gases (CO2, O2 and N2) is:

Total pressure = Partial pressure CO2 + Partial pressure O2 + Partial pressure N2

0.070atm CO2 are:

0.070atm * (760mmHg / 1atm) 53.2mmHg

Replacing:

930mmHg = 53.2mmHg + 680mmHg + Partial pressure N2

Partial Pressure N2 = 196.8mmHg

In kPa -101.325kPa = 760mmHg-

196.8mmHg * (101.325kPa / 760mmHg) =

<h3>26.2kPa is the partial pressure of nitrogen</h3>
