For each of the following, write the measurement in terms of an appropriate prefix and base unit. a. The mass of magnesium per milliliter in a sample of blood serum is $0.0186 \mathrm{~g}$. b. The radius of a carbon atom is about $0.000000000077 \mathrm{~m}$. c. The hemoglobin molecule, a component of red blood cells, is $0.0000000065 \mathrm{~m}$ in diameter. d. The wavelength of a certain infrared radiation is $0.00000085 \mathrm{~m}$

Key Concepts

Unit Conversion

Unit conversion involves translating a measurement from one unit or notation to another, often by applying conversion factors or shifting decimal places in the context of powers of ten. In problems of this type, it entails re-expressing a given measurement using an appropriate SI base unit paired with a metric prefix to reflect its magnitude accurately.

Scientific Notation

Scientific notation is a method for expressing numbers as a product of a number between 1 and 10 and a power of ten. This representation is especially useful in the metric system for handling extremely large or small numbers, making unit conversion and comparison more manageable.

SI Base Units

SI base units, such as meter for length and gram for mass, are the fundamental units in the International System of Units. They serve as the building blocks for all measurements, providing a standardized foundation from which to express derived units and converted measurements.

Metric Prefixes

Metric prefixes are used to signify specific powers of ten associated with SI base units. They allow for a convenient expression of very large or very small quantities by appending terms like milli (10^-3), micro (10^-6), and nano (10^-9) to units, which simplifies calculations and improves clarity.
