Air is a mixture of gases that is about78.0percent n2 by volume. when air is at standard pressure and 25.0 degreec, the n2 component will dissolve in water with a solubility of 4.88 x 10^-4m. what is the value of henry's law constant for n2 under these conditions? express the constant numerically inmoles per liter per atmosphere. =6.26? 10^-4 mol/(l. atm) correct part b as a scuba diver descends under water, thepressure increases. at a total air pressure of 2.73 atm and a temperature of 25.0 degreec, what is the solubility of n2 in a diver's blood? [use the value of the henry's lawconstant calculated in part a, 6.26 x 10^-4mol/(l. atm). assume that the composition of the air in the tank is the sameas on land and that all of the dissolved nitrogen remains in theblood. express your answer numerically inmoles per liter. solubility =mol/l

Explanation:

(a) According to the Henry's law, the solubility is equal to the product between the Henry's law constant and the partial pressure of a gas:

Air is at standard pressure:

Therefore, its partial pressure is:

Solving for the Henry's constant:

(b) Using the constant we've found in the previous part, we know that:

In this case, the percentage is kept the same, however, the total air pressure is:

Substituting the variables:

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
