Answer:
Explanation:
We know we will need a balanced chemical equation with masses and molar masses, so, let's gather all the information in one place.
You don't tell us what the reaction is, but we can solve the problem so long as we balance the OH.
M_r: 58.32
Mg(OH)₂ + … ⟶ … + 2HOH
m/g: 58.3
(a) Moles of Mg(OH)₂
(b) Moles of H₂O
The molar ratio is 2 mol H₂O = 1 mol Mg(OH)₂.
The reaction will form 
of water.

Below
Explanation:
Salt solution, aka saline solution, is a homogeneous mixture. This means that the mixtures composition is completely uniform throughout. If you were to look at a saline solution, it would just look like plain water because the salt is dissolved (it looks the exact same in the entire mixture).
Something like bean soup would be an example of a heterogeneous mixture. You can see all the beans and vegetables as components of one mixture.

Answer:
Explanation:
As can be seen in the Figure in a face-centered cubic unit cell you have:
- Six halves of atoms
- Eight 1/8 of atom (1 in each corner)
In total:
Now, each side of the cell is 234 picometers (2.34e-8 cm) long
Atoms per cm3:
