How many atoms are in MgOH2?

Answer 1

1 magnesium

2 oxygen

2 hydrogen

Answer 2

As written '4'.

However, I think you have written the formula incorrectly. It should be 'Mg(OH)2'. Magnesium hydroxide.

NB The brackets are needed to indicate that there are two oxygens and two hydrogens ; viz two hydroxides. Without the brackets it is meaningless.

Magnesium hydroxide has five(5) atoms viz;

1 x magnesium

2 x oxygen

2 x hydrogen

Answer 3

If the questioner intended to write the formula as Mg(OH)2, there are two hydrogen atoms, two oxygen atoms, and one magnesium atom, fora total of 5 atoms.

Answer 4

There are 5 atoms in MgOH2: 1 magnesium atom (Mg), 2 oxygen atoms (O), and 2 hydrogen atoms (H).

Answer 5

5

Answer 6

Mg(OH)2
