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.
If the battery was removed, the energy produced by the battery would not be able to continue its path along the circuit.
The experimental procedure would provide evidence that plants need
nitrogen to grow is by
- Identical plants are placed in two air-tight containers with sufficient exposure to sunlight.
- One container has nitrogen gas, and the other has room air. The scientist measures plant growth
It is necessary to use identical plants during the experiment as plants have
different rates of nitrogen absorption from the soil. It should also be done in
air-tight containers called terrariums to prevent loss or contamination of the
gases with other elements/compounds.
The identical plants containing nitrogen and room air should both be
measured for the growth difference between them.
