First of all, it should be written as Mg(OH)2.
There is 1 Mg, 2 O, and 2 H.
Mg has 12 protons, O has 8 protons, and H has 1 proton.
So, 12 + 2 x 8 + 2 x 1 = 30 protons.
The answer is one mole.
The name for the ionic compound MgOH2 is magnesium hydroxide.

MgOH2 is a base. It is also known as magnesium hydroxide and is commonly used as an antacid to neutralize stomach acid.
Magnesium hydroxide
MGOH2 is an inorganic compound. It is the chemical formula for magnesium hydroxide, which is a compound made up of magnesium, hydrogen, and oxygen atoms.
Mg(OH)2 is a base. It is an alkaline earth metal hydroxide that dissociates in water to form hydroxide ions, which can accept protons from acids to neutralize them.
2NaCl + Mg(OH)2 --> MgCl2 + 2NaOH Make sure to put the parentheses around the hydroxide. There is a difference between Mg(OH)2 and MgOH2.
Osmium has as many protons as it needs
2 protons
It has 26 protons.
Bohrium has 107 protons.
