What is the Calculation of relative formula mass of Mg(OH)2.?

The relative formula mass of Mg(OH)2 can be calculated by adding the atomic masses of all the elements in the compound. The Atomic Mass of magnesium (Mg) is 24.305 amu, oxygen (O) is 15.999 amu, and hydrogen (H) is 1.008 amu. Therefore, the relative formula mass of Mg(OH)2 is calculated as follows: Mg = 24.305 amu, O = 15.999 amu x 2 = 31.998 amu, H = 1.008 amu x 2 = 2.016 amu. Adding these values together gives a total relative formula mass of Mg(OH)2 as 24.305 + 31.998 + 2.016 = 58.319 amu.
