How Many Atoms Are There In 53.95 Grams Of Zinc?
Introduction
Understanding the number of atoms present in a given mass of a substance is a fundamental concept in chemistry. Zinc, a transition metal, is widely used in various applications, including batteries, alloys, and as a coating for other metals. In this article, we will explore the process of calculating the number of atoms in 53.95 grams of zinc.
Atomic Mass of Zinc
To begin, we need to determine the atomic mass of zinc. The atomic mass of an element is the average mass of a single atom of that element, expressed in atomic mass units (amu). The atomic mass of zinc is 65.38 amu.
Avogadro's Number
Avogadro's number is a fundamental constant in chemistry, representing the number of particles (atoms or molecules) in one mole of a substance. One mole of any substance contains 6.022 x 10^23 particles. This number is a universal constant and is used to convert between the number of moles and the number of particles.
Calculating the Number of Moles of Zinc
To calculate the number of moles of zinc in 53.95 grams, we can use the formula:
Number of moles = mass of substance / atomic mass
Substituting the values, we get:
Number of moles = 53.95 g / 65.38 g/mol = 0.823 mol
Calculating the Number of Atoms
Now that we have the number of moles, we can calculate the number of atoms using Avogadro's number:
Number of atoms = number of moles x Avogadro's number
Substituting the values, we get:
Number of atoms = 0.823 mol x 6.022 x 10^23 atoms/mol = 4.977 x 10^23 atoms
Conclusion
In this article, we calculated the number of atoms in 53.95 grams of zinc using the atomic mass of zinc and Avogadro's number. The result shows that there are approximately 4.977 x 10^23 atoms in 53.95 grams of zinc.
