Use the prefix multipliers to express each measurement without exponents. c. 1.5 * 109 g

Key Concepts

Metric Prefixes

Metric prefixes are used to denote specific powers of ten in the metric system, allowing for easier expression of large or small quantities. For example, 'giga-' represents 10^9, so 1.5 * 10^9 g can be expressed as 1.5 gigagrams (Gg). Understanding these prefixes is essential for converting and simplifying measurements.

Scientific Notation

Scientific notation is a method of expressing numbers as a product of a coefficient and a power of ten, which simplifies calculations and comparisons. In this case, 1.5 * 10^9 g is in scientific notation, where 1.5 is the coefficient and 10^9 indicates the scale of the measurement. Converting to metric prefixes involves recognizing the power of ten.

Unit Conversion

Unit conversion is the process of converting a measurement from one unit to another, often involving multiplication by a conversion factor. In this scenario, converting grams to gigagrams requires understanding the relationship between these units, specifically that 1 Gg equals 10^9 g. This knowledge is crucial for accurately expressing measurements in different units.
