is this true or false?
5) Density has units of grams per cubic centimeter.
It may have units of g/cc. But the unit used is strictly up to the individual calculating. It may be in kg/cubic meter or any of a number of other conversions.
The statement "Density has units of grams per cubic centimeter" is not entirely true. While grams per cubic centimeter (g/cm³) is a commonly used unit for density, density can actually have different units depending on the system of measurement being used.
Density is defined as mass divided by volume, so the units for density can be derived from the units of mass and volume. In the metric system, the unit for mass is grams (g), and the unit for volume is cubic centimeters (cm³). Therefore, in the metric system, density is often expressed in units of grams per cubic centimeter (g/cm³).
However, density can also be expressed in other units. For example, in the International System of Units (SI), the unit for mass is the kilogram (kg), and the unit for volume is the cubic meter (m³). In this case, density would be expressed in units of kilograms per cubic meter (kg/m³).
Furthermore, there are other unit conversions that can be used, such as pounds per cubic inch (lb/in³) or ounces per fluid ounce (oz/fl oz), depending on the specific context or application.
So, while the statement is partially true that density can be expressed in grams per cubic centimeter (g/cm³), it is important to note that density can have different units depending on the specific measurement system being used.
