Answer 1

Answer:

Answer 2

The proportion of the mass of one chemical element to that of another  chemical element is a mass: ratio.

Mass ratio is also referred to as percent composition by mass and it can be defined as a proportion of the mass of an element to the mass of another chemical element.

Mathematically, mass ratio is calculated by using the following formula;

$Mass \; ratio = \frac{Mass \;of \;element \;A}{Mass \;of \;element \;B}$

For example, if the mass of Sodium is 10 grams and that of Chlorine is 20 grams. We would calculate the mass ratio as follows:

$Mass \; ratio = \frac{10}{20}$

Mass ratio = 0.5 grams.
