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.
1 mol of Br = 79.9 g
15.7 g / 79.9 g = 0.196 moles of atoms
The density of an object or quantity of matter is its mass divided by its volume.
