salt and water solution is a homogeneous mixture
<u>Explanation:</u>
Homogeneous mixtures generally termed as solutions, have an identical similar occurrence and form throughout (the prefix "homo" means the same). Solutions consist of particles as tiny as fragments or molecules. For instance, a sugar solution is homogeneous because only transparent liquids can be seen. Homogeneous mixtures only have individual phase: gas, liquid or solid.
Solvent: normally the material in the greater amount. The material used to dissolve the solute or solutes. Example: water.
Solute: ordinarily the substance in the lesser amount. The substance dissolved by the solvent. Example: salt
Salt and water solution is homogeneous because only transparent liquids can be seen.

DENSITY
Density is defined as mass per unit volume.
d =
m
V
Example:
A brick of salt measuring 10.0 cm x 10.0 cm x 2.00 cm has a mass of 433 g. What is its density?
Step 1: Calculate the volume
V = lwh = 10.0 cm × 10.0 cm × 2.00 cm = 200 cm³

We can rearrange this to get the expression for the mass.
m = d×V
Example:
