Answer:
See the answer below
Explanation:
The best approach would be to <u>pour the liquid from the large reagent bottle into a small-size beaker or reagent bottle first</u>, before measuring the required quantity out into the reaction vessel. This is necessary in order to maintain safety in the laboratory.
Pouring the liquid directly from the large reagent bottle into the measuring cylinder or directly into the reaction bottle can compromise safety in the laboratory. The liquid might splash out and cause harm to the handler or create other harmful circumstances in the laboratory.

Answer : The molar concentration of solution is 
Explanation :
Using Beer-Lambert's law :
where,
A = absorbance of solution = 0.614
C = molar concentration of solution = ?
l = path length = 1.0 cm
= molar absorptivity coefficient = 
(assume)
Now put all the given values in the above formula, we get:
Therefore, the molar concentration of solution is
