Answer:
The answer is
<h2>1479.60 mL</h2>
Explanation:
In order to calculate the volume needed we use the formula

where
C1 is the concentration of the stock solution
V1 is the volume of the stock solution
C2 is the concentration of the diluted solution
V2 is the volume of thevdiluted solution
From the question
C1 = 1.45 M
V1 = 25 mL
C2 = 0.0245 M
So we have

We have the final answer as
<h3>1479.60 mL</h3>
Hope this helps you
Answer:
This question is incomplete
Explanation:
This question is incomplete but generally it seem to test the knowledge of accuracy. Accuracy is the closeness of a measured value to the specific or actual value of the substance being measured. Hence, the smaller the entire scale that can contain all the substance being measured, the higher the possibility of accuracy to be achieved. For example, a pen of 10.4 cm in length can be better/accurately measured (length) with a 30 cm meter rule than a 1 m meter rule.
From the question, the 50 mL beaker will provide a "more accurate" measurement of the volume of the bromine than the 100 mL beaker if the 50 mL beaker can contain all the sample of bromine water provided.
An exothermic process releases heat, causing the temperature of the immediate surroundings to rise. An endothermic process absorbs heat and cools the surroundings
