Introduction

In chemistry, understanding the mass of individual atoms is crucial for various calculations and applications. The mass of a single oxygen atom is approximately $2.7 \times 10^{-23}$ grams. In this article, we will explore the best estimate of the mass of 40,000 oxygen atoms.

Understanding Atomic Mass

The atomic mass of an element is the mass of a single atom of that element. In the case of oxygen, the atomic mass is approximately $2.7 \times 10^{-23}$ grams. This value is a fundamental constant in chemistry and is used to calculate the mass of atoms and molecules.

Calculating the Mass of 40,000 Oxygen Atoms

To calculate the mass of 40,000 oxygen atoms, we need to multiply the mass of a single oxygen atom by 40,000.

Mass of a Single Oxygen Atom

The mass of a single oxygen atom is approximately $2.7 \times 10^{-23}$ grams.

Mass of 40,000 Oxygen Atoms

To calculate the mass of 40,000 oxygen atoms, we multiply the mass of a single oxygen atom by 40,000:

$2.7 \times 10^{-23} \text{ grams} \times 40,000 = 1.08 \times 10^{-18} \text{ grams}$

Conclusion

The best estimate of the mass of 40,000 oxygen atoms is $1.08 \times 10^{-18}$ grams. This calculation demonstrates the importance of understanding atomic mass in chemistry and its applications.

Answer

The correct answer is A. $1.08 \times 10^{-18}$ grams.

Discussion

The mass of individual atoms is a fundamental concept in chemistry. Understanding the mass of atoms and molecules is crucial for various calculations and applications. In this article, we calculated the mass of 40,000 oxygen atoms using the atomic mass of oxygen.
