One gram of salt in 100 liters of water could be considered a <em><u>dilute solution</u></em>.
<h3><u>Explanation</u>;</h3>
<em><u>A solution is a mixture that is composed of two or more substances. It is formed when one substance (solute) dissolves on another called solvent. </u></em>
Solutions are homogeneous mixtures as the substances in it are always in the same phase. <em><u>A solution may be concentrated or dilute depending on the amount of solute or solvent in the solution.</u></em>
<u>A dilute solution has more solvent that solute while a concentrated solution has more solute than the solvent. In this case, </u><em><u>a solution containing 1 g of slat which is the solute in a 100 liters of water is an example of dilute solution.</u></em>
The gravity of the Sun keeps the planets in their orbits. They stay in their orbits because there is no other force in the Solar System which can stop them.
