Answer:
Explanation:
Using the Ideal Gas Law we have 
and the number of moles n could be expressed as 
, where m is the mass and M is the molar mass.
Now, replacing the number of moles in the equation for the ideal gass law:
If we pass the V to divide:
As the density is expressed as 
, we have:
Solving for the density:
Then we need to convert the units to the S.I.:
Finally we replace the values:
Answer:
44
Explanation:
protons and electrons have the same number:)
The correct answers from the choices are:
a. Reduce inflammation locally
b. Antagonize H1 receptors
c. May be administered orally
<span>d. Are systemically distributed
</span><span>Antihistamines are drugs that are H1 antagonists or blockers, may be administered orally, are distributed systemically, and do not directly reduce nasal congestion.</span>
In that case, the salt<span> would be the </span>solvent<span> and the </span>water<span> the </span><span>solute.
So, it would be solution!
