Answer:
N = n× l
N = number of entities
n= moles
l = Avogadro's constant = 6.023 × 10^23
3.01 × 10^ 23 = n * 6.023 × 10^23
n = 3.01 × 10^23/6.023 × 10^23
n= 0.5moles
Molar mass = mass/ number of moles
Molar mass = 56
mass = 56 × 0.5
= 28g
Hope this helps.
Everything has chemical properties it depends on the reactivity and the reactivity of the other element and what form it is in
All organisms share certain characteristics of life, for example, all living things are made of cells and they must reproduce to make the next generation. Without these characteristics, there is no life.

A evole like a pokemon does to its environment.
The error is in the formula is bracket so the correct is Mg(OH)₂
The incorrect or error in the formula is bracket that would be that the compound contain only 1Mg atom and 1 oxygen atom and 2 hydrogen atom but is wrong when you write it in an electron dot diagram you will see that it is wrong there be unshared paired of electron and the correct formula is Mg(OH)₂
Know more about Mg(OH)₂
