5. A scuba driver has a 10 L tank that is filled with Nitrox or otherwise known as "enriched air. Therefore, it contains 5.00 g of oxygen gas (O2) and 8.31 g of nitrogen gas (N2). The pressure of the tank is 179.6 atm. What is the partial pressure of both oxygen and nitrogen?

Answer : The partial pressure of both oxygen and nitrogen is, 61.8 atm and 117.8 atm respectively.

Explanation :

First we have to calculate the moles of and

and,

Now we have to calculate the mole fraction of and

and,

Now we have to calculate the partial pressure of both oxygen and nitrogen.

According to the Raoult's law,

where,

= partial pressure of gas

= total pressure of gas  = 179.6 atm

= mole fraction of gas

and,

Thus, the partial pressure of both oxygen and nitrogen is, 61.8 atm and 117.8 atm respectively.

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.
