The Protons and Electrons are equal to the atomic number (41). And the mass number (162) <span>is equal to the sum of the number of </span>protons<span> and </span>neutrons<span> in the nucleus. So to find the number of Neutrons, just subtract 41 (number of protons) from 162 (mass). That means element X has 121 Neutrons.</span>

A Tomato Has A Proton Concentration Of 0.00006 M. How Would You Calculate The PH?

Debora [2.8K]

Answer:

Option b. is correct

Explanation:

If hydronium ion concentration $H_3O^+$ is given then pH is given by $-log[H_3O^+]$

The hydronium ion refers to the hydrogen ion in aqueous solution.

A Tomato has A Proton Concentration Of 0.00006 M

Here, 0.00006 is equal to 6 × $10^{-5}$

So,

pH is given by - log [6 × $10^{-5}$ ]

Option b. is correct
