Every year in the United States, about 12 million tons of magnesium metal are used to manufacture the sacrificial anodes that prevent the corrosion of iron structures. The required magnesium can be obtained by processing seawater. Seawater has a density of 1.025 g/mL and one kilogram of seawater contains 1.4 g of magnesium. What volume of seawater, in cubic kilometers, would need to be processed to provide theU.S. with a one-year supply of magnesium?

Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.
