How many sulfur atoms are there in 5.52 mol of sulfur?

Verified step by step guidance

1. Step 1: Understand the concept of a mole. In chemistry, a mole is a unit that is used to measure the amount of a substance. It is defined as the amount of any substance that contains as many entities (atoms, molecules, ions, etc.) as there are in 12 grams of carbon-12. This number is known as Avogadro's number, and it is approximately 6.022 x 10^23.
2. Step 2: Identify the given information. In this problem, we are given that we have 5.52 moles of sulfur.
3. Step 3: Use Avogadro's number to calculate the number of sulfur atoms. Since one mole of any substance contains approximately 6.022 x 10^23 entities, we can multiply the number of moles of sulfur by Avogadro's number to find the number of sulfur atoms.
4. Step 4: Set up the calculation. The calculation should look like this: (5.52 moles of sulfur) x (6.022 x 10^23 atoms/mole).
5. Step 5: Perform the calculation. When you multiply the number of moles by Avogadro's number, you will get the number of sulfur atoms.

Key Concepts

Mole Concept

The mole is a fundamental unit in chemistry that quantifies the amount of substance. One mole contains Avogadro's number of entities, which is approximately 6.022 x 10²³ particles, atoms, or molecules. This concept allows chemists to convert between the mass of a substance and the number of atoms or molecules it contains.

Avogadro's Number

Avogadro's number (6.022 x 10²³) is the number of atoms, ions, or molecules in one mole of a substance. It provides a bridge between the macroscopic scale of substances we can measure and the microscopic scale of individual particles. Understanding this number is crucial for calculating the number of atoms in a given amount of substance.

Stoichiometry

Stoichiometry is the area of chemistry that deals with the relationships between the quantities of reactants and products in chemical reactions. It allows for the calculation of how many atoms or molecules are present in a given amount of substance, using the mole concept and Avogadro's number to facilitate these conversions.
