Step-by-step solution

Representation of the mass of a carbon atom

The mass of a carbon atom is given as 0.00000000000000000000002 gram. This can be rewritten in scientific notation to make it simpler to read. In scientific notation, the mass of the carbon atom is represented as \(2 \times 10^{-23}\) grams.

Key concepts

Atomic Mass

Understanding the atomic mass is crucial in the field of chemistry. It refers to the mass of a single atom, which is exceedingly small and can be challenging to express in standard decimal form due to its size. Atomic mass can be measured in atomic mass units (amu), also known as daltons.

For instance, in the exercise, the mass of a carbon atom is given in grams, a standard unit in the metric system. The atomic mass provides vital information that scientists use to predict the behaviors of elements in different chemical reactions. It also plays a significant role in calculating the molar mass of compounds, which is essential for quantitative chemical analysis.

Since atomic masses are typically very small numbers, it's common practice to express them in scientific notation for simplicity and accuracy. For example, the precise atomic mass of a carbon atom is approximately 12 amu, but when measured in grams, it is a much more minuscule number, making scientific notation an indispensable tool.

Carbon Atom

The carbon atom is one of the building blocks of life and is the central element in organic chemistry. Understanding carbon's properties, such as its atomic mass, is essential for comprehending molecular structures and reactions.

Carbon has unique characteristics, including its ability to form four covalent bonds with other atoms, which allows for the formation of complex molecules. It is these bonds that make carbon the backbone of organic compounds, ranging from simple gases like methane, CH₄, to complex proteins and DNA molecules found in living organisms.

The carbon atom's versatility is due to its electronic configuration, which allows it to easily share electrons with other elements. This behavior is at the heart of virtually all the chemical processes that sustain life, illustrating why the study of carbon, often known as carbon chemistry, is so vital.

Scientific Notation in Algebra

Scientific notation is a convenient way to express very large or very small numbers in algebra. This notation simplifies calculations, making it easier to handle these numbers during mathematical operations. It is written as a product of two numbers: a coefficient and a power of 10, where the coefficient is a number greater than or equal to 1 and less than 10.

In the given exercise, the atomic mass of carbon was converted into scientific notation. This was achieved by identifying the most significant digit, 2, and counting the number of places it has moved from the original decimal position. That number becomes the exponent of 10, while the coefficient remains 2. Here, the carbon atom’s mass was rewritten as \(2 \times 10^{-23}\) grams.

This notation is not only used in chemistry but also throughout the sciences and mathematics, whenever dealing with extremely large or small quantities. It is also a key skill for working with calculators and computers, which often display results in scientific notation to accommodate their digital displays.
