Answer: <u>Molarity of solution is 0.751 M. </u>
Reason:
Given: weight of solute (LiF) = 17.8 g, volume of solution = 915 ml = 0.915 l
We know that,
Molarity = </span>
<span>
<em>Molecular Weight of LiF = 25.9 g/mol. </em>
</span>∴<span>,
Molarity = </span>
<span> =
0.751 M</span>

Yea.....where is the article and the 6 questions?
Answer : The concentration of AB after 14.0 s is, 0.29 M
Explanation :
The expression used for second order kinetics is:
where,
k = rate constant =
t = time = 14.0 s
= final concentration = ?
= initial concentration = 1.50 M
Now put all the given values in the above expression, we get:
Therefore, the concentration of AB after 14.0 s is, 0.29 M
Explanation:
A structure in which valence electrons are depicted by dots is called a lewis structure.
For example, atomic number of oxygen is 8 and its electronic distribution is 2, 6.
Hence, the electron dot structure for molecule is as depicted in the picture attached.
