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
