The concentration of N2 in blood at 37 °C (body temperature) and atmospheric pressure (partial pressure of N2 = 0.80 atm) is 0.0
devlian [24]

Answer:

volume  = 0.285 L

Explanation:

Henry constant is given as

Henry constant  =  \frac{C}{P}

Where C  is concentration

P is atmospheric pressure

Henry\ constant = \frac{0.00056}{0.80} = 0.0007 M/atm

when atmospheric pressure 4 atm

solubility = K_H\times P

              = 0.0007 \times 4 = 0.0028 M

In 5 litere blood , moles of N_2 = Molarity \times volume

                                                     = 0.0028 \times 5 = 0.014

At surface moles  = 0.0056 \times 5 = 0.0028

Moles of N_2 release = 0.014 - 0.0028 = 0.0112

Mass of N_2 = 0.0112 \times 28 = 0.314 g

T = 37 + 273 = 310 K

VOLUME = \frac{nRT}{P}

= \frac{0.0112\times 0.0821\times 310}{1}

volume  = 0.285 L
