Which quantity can be calculated for a solid compound, given only the formula of the compound and the periodic table of the elements

The correct answer is the percent composition by mass of each element in the compound

Explanation:

The molar mass is the mass that contains one mole of a compound. A mole is a unit of the International System of units and represents a number of atoms, molecules or more generally of particles.    

So, as mentioned, the molar mass is the amount of mass that a substance contains in one mole. It is usually expressed in grams / mol.

In the periodic table, you can find the molar mass of the elements, also called atomic mass or atomic weight, at the bottom of the element.

Given the formula of the compound, to calculate the molecular mass of a compound, also called molecular mass or weight, we must add the molar mass of the elements (using the periodic table, observing the atomic mass of the elements) of the compound multiplied by the times they appear in the molecule or compound.

In any chemical compound that is formed by two or more different elements, these are present in said compound in a given percentage amount or composition. Then the mass percentage composition is the mass percentage of each element that makes up a compound. It is obtained by dividing the mass of element X by the total mass of the compound and the result multiplied by 100. The mass of each element, as mentioned, can be obtained in the periodic table. And from the atomic mass the molar mass of the compound can be obtained by multiplying the quantity of each element's appearance by its atomic mass and adding each of the masses of said elements. Finally, knowing the mass of each element and the molar mass of the compound it is possible to know the percentage mass composition of each element in the compound.

So, the correct answer is the percent composition by mass of each element in the compound
