If 6.02 * 1023 atoms of element Y have a mass of 83.80 g, what is the identity of Y?

Key Concepts

Avogadro's Number

Avogadro's number, approximately 6.02 x 10^23, is the number of atoms, molecules, or particles in one mole of a substance. This constant is fundamental in chemistry for converting between the number of particles and the amount of substance in moles, allowing chemists to relate macroscopic quantities to atomic-scale properties.

Molar Mass

Molar mass is the mass of one mole of a substance, typically expressed in grams per mole (g/mol). It is calculated by summing the atomic masses of all the atoms in a molecule. In this question, knowing the molar mass of element Y will help identify the element based on the given mass of 83.80 g for 6.02 x 10^23 atoms.

Periodic Table of Elements

The periodic table organizes all known chemical elements based on their atomic number, electron configuration, and recurring chemical properties. Each element has a unique atomic mass, which can be used to identify it when given the mass of a specific number of atoms. In this case, the molar mass derived from the given data can be matched to an element in the periodic table to determine the identity of Y.
