The pH of a solution with a hydronium ion concentration of 2.1 x 10^-8 M is 7.68. This can be calculated by taking the negative logarithm (base 10) of the hydronium ion concentration. The formula for pH is pH = -log[H3O+].

A solution with pH of 2 has a hydrogen ion concentration of 1.0 x 10-2 mols/L

∙ 13y agopH = -log[H3O+] ----> pH = -log(2.1x10^-8) ----> pH = 7.68

∙ 8y agoWhat is the hydronium ion concentration of an aqueous solution with a pH = 2.00?

pH = 2.00
Then by inverse function of mathematics.
[H^+] = 10^(-pH)
Henc subctituting
[H^+] = 10^(-2) =
[H^+] = 0.01

2.1 cm is equal to 21 mm.
Inch and centimeter are both linear units of measurement. They are used to measure small distance. The conversion is done by multiplying the inch measurement by 2.54. The above unit in centimeters equals 2.1 cm (Approximately).
One number that multiplied by another equals 21 is 3, since 3 x 7 = 21.
28 times 21 equals 588.
21 times 12 equals 252.
3 and 7 multiplies to 21 and equals to 10
The statement 10 plus 21 equals 31 in total. It can also be written as 10 + 21 = 31.
21 is the only solution of that equation.
21 + 10 = 31
The solution is k = 9.

10 + 11 = 21
No you can not prove that 9 +10 = 21.
