What does density mean?
- The density of an area refers to the quantity of things—which may include people, animals, plants, or objects—there are in it.
- Divide the number of objects by the area's measurement to determine density.
- A country's population density is calculated by dividing its total population by its area, expressed in square kilometers or miles.
We can calculate the volume of the cube by cubing the side of the cube.
Volume of cube = ( 1.000 cm)³
= 1.000 cm³
We can now determine the amount of lead in the cube by multiplying by the density. Because we know we have a 1.000 cubic centimeter and that lead has a density of 11.35 grams per cubic centimeter, we have 11.35 grams of lead.
= ( 1.000 cm³) ( 11.35 )
= 11.35 g

Economy - If there isn't a sustainable economy, it won't be able to support many people so instead they are limited.
Weather- If a place is too warm or too cold it can affect the population. The weather may be seen as harsh.
Government- If people are not agreeing with the government and are against, many will leave. They won't be able to withstand it.
Overpopulation- If there is too many people, they may restrict how many babies you can have and how many people can live there. China, a co

The pH classification line (potential of hydrogen) starts at 0 and ends at 14. Solutions that have a pH below 7 (which is the neutral), have more acidic characteristics. Solutions, on the other hand, that have their hydrogen potential greater than 7, have basic aspects. A substance with pH 8, therefore, has a basic <span>characteristic.
