Answer : The mass of nitrogen dissolved is, 79.4 grams
Explanation :
The Raoult's law for liquid phase is:
where,
= partial vapor pressure of nitrogen = ?
= total pressure = 1.0 atm
= mole fraction of nitrogen = 0.78
Now put all the given values in the above formula, we get:
Now we have to calculate the mass of nitrogen.
Using ideal gas equation:
where,
P = pressure of gas = 0.78 atm
V = volume of gas = 89.0 L
T = temperature of gas =
R = gas constant = 0.0821 L.atm/mole.K
w = mass of gas = ?
M = molar mass of nitrogen gas = 28 g/mole
Now put all the given values in the ideal gas equation, we get:
Therefore, the mass of nitrogen dissolved is, 79.4 grams
