The M stands for molar, so it would be 5.0 molar. is that what you need?
The ionic charge of oxygen is -2.
Hope this helps! ;)
In an aqueous solution, the hydronium ion concentration is equivalent to the hydrogen ion concentration because the hydrogen ion exists as the hydronium ion. The pH of pure water is 7, and:
pH = -log[H+]
7 = -log[H+]
[H+] = 1 x 10⁻⁷
Therefore, the hydronium ion concentration in pure water is also 1 x 10⁻⁷.
Playing outside or going bike riding
It results in a combustion reaction
