The answer is False for sodium bromide it would be NaBr
A sodium atom forms NA+1 ion by losing two electrons
Dilution law is given as:
(1)
where, 
= molarity of initial concentrated solution.
= volume of initial concentrated solution.
= molarity of final diluted solution.
tex]V_{2}[/tex] = volume of final diluted solution.
Volume of initial concentrated solution of 
= 100.0 mL
Molarity of initial concentrated solution of = 5.50 M
Volume of final diluted solution of = 0.950 M
Put the values in formula (1),
Hence, final diluted volume of the solution is 
.
Answer:
The solution is 10^-2 or 0.01M in HCl.
Explanation:
meaning of pH is "power of hydrogen".
what is the molar concentration of a HCl solution with pH=2?
Let say pH=2
[H+]=10^-2M
HCL is a strong acid that dissociates completely:
[H+]=[HCL]
Therefore solution is 10^-2 or 0.01M in HCL.
