Answer:
44.8 litres is the answer to the question
<h2>
Hello!</h2>
The answer is:
There are 732.24 grams of Dinitrogen Pentoxide
in 6.78 moles of the same compound.
<h2>
Why?</h2>
The dinitrogen pentoxide, or nitrogen pentoxide, is a rare salt that consists of anion and cations, and it's an important compound when preparing some kinds of explosives.
So, to answer the question, first, need to look for the molecular formula of the dinitrogen pentoxide, then, use it to calculate the mass in gram of 6.78 moles of the same compound.
The dinitrogen pentoxide formula is:
![N_{2}O_{5}](https://tex.z-dn.net/?f=N_%7B2%7DO_%7B5%7D)
Where, the molar mass of each element are:
![N=\frac{14g}{mol}](https://tex.z-dn.net/?f=N%3D%5Cfrac%7B14g%7D%7Bmol%7D)
![O=\frac{16g}{mol}](https://tex.z-dn.net/?f=O%3D%5Cfrac%7B16g%7D%7Bmol%7D)
Calculating the molar mass of the compound, we have:
![N_{2}O_{5}=2*(\frac{14g}{mol})+5*(\frac{16g}{mol})](https://tex.z-dn.net/?f=N_%7B2%7DO_%7B5%7D%3D2%2A%28%5Cfrac%7B14g%7D%7Bmol%7D%29%2B5%2A%28%5Cfrac%7B16g%7D%7Bmol%7D%29)
![N_{2}O_{5}=(\frac{28g}{mol})+(\frac{80g}{mol})=(\frac{108g}{mol}](https://tex.z-dn.net/?f=N_%7B2%7DO_%7B5%7D%3D%28%5Cfrac%7B28g%7D%7Bmol%7D%29%2B%28%5Cfrac%7B80g%7D%7Bmol%7D%29%3D%28%5Cfrac%7B108g%7D%7Bmol%7D)
Now, calculating what is the mass of 6.78 of
, we have:
![mass=moles*MolarMass=6.78mol(N_{2}O_{5})*\frac{108g}{mol}=732.24g(N_{2}O_{5})](https://tex.z-dn.net/?f=mass%3Dmoles%2AMolarMass%3D6.78mol%28N_%7B2%7DO_%7B5%7D%29%2A%5Cfrac%7B108g%7D%7Bmol%7D%3D732.24g%28N_%7B2%7DO_%7B5%7D%29)
So, there are 732.24 grams of Dinitrogen Pentoxide
in 6.78 moles of the same compound.
Have a nice day!
Answer:
not valid
Explanation:
Expert judgment is a useful validation method to verify the reliability of an investigation that is defined as “an informed opinion of people with experience in the subject, who are recognized by others as qualified experts in it, and who can give information, evidence, judgments and assessments ”
After submitting an instrument for comparison to the consultation and expert opinion, it must meet two quality criteria: validity and reliability. The validity of content is often established based on two situations, one that concerns the design of a test and the other, the validation of an instrument subject to translation and standardization procedures to adapt it to different cultural meanings. It is here that the task of the expert becomes a fundamental task to eliminate irrelevant aspects, incorporate those that are essential and / or modify those that require it.
