Answer:
The answer is
<h2>0.95 atm</h2>Explanation:
To solve the question we use the following conversion
That's
1 mmHg 0.0013 atm
So we have
If 1 mmHg 0.0013 atm
Then 732 mmHg will be
732 × 0.0013 atm
We have the final answer as
<h3>0.95 atm</h3>Hope this helps you
The question is incomplete, here is the complete question:
Solid cesium iodide has the same kind of crystal structure as CsCl which is pictured below: If the edge length of the unit cell is 456.2 pm, what is the density of CsI in
The image is attached below.
<u>Answer:</u> The density of CsI is
<u>Explanation:</u>
To calculate the density of metal, we use the equation:
where,
= density
Z = number of atom in unit cell = 2 (BCC)
M = atomic mass of CsI = 259.8 g/mol
= Avogadro's number =
a = edge length of unit cell = (Conversion factor:
)
Putting values in above equation, we get:
Hence, the density of CsI is
