Answer: The density of the given vapor is 0.939 g/L.
Explanation:
Given: Pressure = 233 mm Hg (1 mm Hg = 0.00131579 atm) = 0.31 atm
Temperature = = (25 + 273) K = 298 K
According to the ideal gas equation,
where,
P = pressure
V = volume
m = mass
M = molar mass
R = gas constant = 0.0821 L atm/mol K
T = temperature
This formula can be re-written as follows.
(where,
)
Hence, formula used to calculate density of diethy ether (molar mass = 74.12 g/mol) vapor is as follows.
Substitute values into the above formula as follows.
Thus, we can conclude that the density of the given vapor is 0.939 g/L.
