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.

The mass will increase think of it being on a graph the y axis as mass and x axis as volume density would be the slope of the line so as mass increases so does volume and vise versa
The answer is 58.6934. We assume you are converting between grams Nickel and mole. You can view more details on each measurement unit: molecular weight of Nickel or moles The molecular formula for Nickel is Ni. The SI base unit for amount of substance is the mole. 1 grams Nickel is equal to 0.017037690779543 mole.
