Answer:
0.85 Molar Na2O
Explanation:
Determine the moles of sodium oxide, Na2O, in 10 grams by dividing by the molar mass of Na2O (61.98 g/mole).
  (10 g Na2O)/(61.98 g/mole) = 0.161 moles Na2O.
Molar is a measure of concentration.  It is defined as moles/liter.  A 1 M  solution contains 1 mole of solute per liter of solvent.  [200 ml water = 0.2 Liters water.]
In this case, we have 0.161 moles Na2O in 0.200 L of solvent.
  (0.161 moles Na2O)/(0.200 L) = 0.85 Molar Na2O

Answer:
 is the solubility of nitrogen gas in a diver's blood.
is the solubility of nitrogen gas in a diver's blood.
Explanation:
Henry's law states that the amount of gas dissolved or molar solubility of gas is directly proportional to the partial pressure of the liquid.
To calculate the molar solubility, we use the equation given by Henry's law, which is:

where,
 = Henry's constant =
 = Henry's constant = 
 = partial pressure of nitrogen
 = partial pressure of nitrogen 
 (Raoult's law)
