Introduction

In chemistry, understanding the relationship between the number of atoms and the mass of an element is crucial for various calculations and applications. The concept of atomic mass and Avogadro's number plays a significant role in this context. In this article, we will explore the mass of carbon that contains $$6 \times 10^{23}$$ carbon atoms, which is equivalent to one mole of carbon.

Understanding Atomic Mass and Avogadro's Number

Atomic mass is the mass of an atom of an element, expressed in units of atomic mass units (amu) or grams per mole (g/mol). Avogadro's number, on the other hand, is a fundamental constant that represents the number of atoms or molecules in one mole of a substance. The value of Avogadro's number is $$6.022 \times 10^{23}$$ particles per mole.

Calculating the Mass of Carbon

To calculate the mass of carbon that contains $$6 \times 10^{23}$$ carbon atoms, we need to use the atomic mass of carbon and Avogadro's number. The atomic mass of carbon is approximately 12.01 g/mol. We can use the following formula to calculate the mass:

Mass = (Number of atoms) x (Atomic mass)

Substituting the values, we get:

Mass = ($$6 \times 10^{23}$$) x (12.01 g/mol)

Performing the Calculation

To perform the calculation, we need to multiply the number of atoms by the atomic mass. This can be done using a calculator or by performing the multiplication manually.

Mass = ($$6 \times 10^{23}$$) x (12.01 g/mol) = $$7.206 \times 10^{25}$$ g/mol

However, we need to convert this value to grams. Since the atomic mass is already in g/mol, we can simply divide the result by Avogadro's number to get the mass in grams.

Mass = $$\frac{7.206 \times 10^{25}}{6.022 \times 10^{23}}$$ = 119.7 g
