Answer;
3 Mg, 6 O, and 6 H
Explanation;
Mg(OH)2 is a compound made up of 1 atom of magnesium, 2 atoms of oxygen, 2 atoms of hydrogen.
3Mg(OH)2, means 3 formula units of Mg(OH)2; the number of atoms present will be; 3 magnesium atoms, 6 oxygen atoms and 6 hydrogen atoms.
That is; 3 × 1 Mg atom = 3 magnesium atom
3 × 2 Oxygen atoms = 6 oxygen atoms
3 × 2 Hydrogen atoms = 6 hydrogen atoms
We have that for the Question,"How many atoms of mg, o, and h are represented by the notation 3 formula units mg(oh)2?" it can be said that
The atoms of mg, o, and h are represented by the notation 3 formula units mg(oh)2 will be
- 3Mg
- 6H
- 6O
From the question we are told
How many atoms of mg, o, and h are represented by the notation 3 formula units mg(oh)2?
Generally
Mg=magnesium atom
H= hydrogen atoms
O= oxygen atoms
Therefore
For 3 formula units mg(oh)2
We have
3*Mg
3*H
3*O
Also the formula Mg(OH)2 has
1Mg
2H
2O
Hence we have that
The atoms of mg, o, and h are represented by the notation 3 formula units mg(oh)2
Will be
- 3Mg
- 6H
- 6O
