Answer:
The amount of NaOH required to prepare a solution of 2.5N NaOH.
The molecular mass of NaOH is 40.0g/mol.
Explanation:
Since,
NaOH has only one replaceable -OH group.
So, its acidity is one.
Hence,
The molecular mass of NaOH =its equivalent mass
Normality formula can be written as:
Substitute the given values in this formula to get the mass of NaOH required.
Hence, the mass of NaOH required to prepare 2.5N and 1L. solution is 100g
Answer:
The answer is
<h2>0.784 g/mL</h2>Explanation:
The density of a substance can be found by using the formula
<h3>From the question
mass of liquid = 9.8 g
volume = 12.5 mL
The density is
We have the final answer as
<h3>0.784 g/mL</h3>Hope this helps you
