What does your percent composition tell you about a molecule? a) it tells you the ratio of elements in the molecular formula b) it tells you the total number of atoms in the molecules c) it tells you how the elements are arranged in the molecule d) it tells you how much of a molecule is made up of each elements

it tells you how much of a molecule is made up of each element

Explanation:

apex

The correct option is (A).

Explanation:

Percent composition of a molecule tells us about the ratio of different elements which are present in the molecule.

For example: is molecular formula for calcium carbonate,in which calcium, carbon and oxygen atoms are present in ratio of 1 : 1 : 3 Or we can also say that molecule of calcium carbonate is made up five atoms out of which one atom is of calcium, one is of carbon atom and remaining three are of an oxygen.

Hence, the correct option is (A).

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
