A density curve is used in statistics to make a rough illustration of a distribution. It is always drawn above the horizontal axis on a graph, and the area is always one.
Know MoreThe area below the density curve represents all observations that fall within the range of the horizontal axis. It is an idealized picture of the data, and is not perfectly accurate. If the density curve is symmetrical, then the mean and the median will be equal. If the distribution skews left, then the mean will be less than the median, and vice versa if the distribution skews right.

Full Answer >Neon is 0.9 grams per liter making it the 113th most dense element out of 118. It is about two-thirds the density of air. Neon is a colorless, odorless, inert, monatomic gas that is part of the noble gases.
Full Answer >At standard temperature and pressure, the density of NaOH, or sodium hydroxide, is 2.13 grams per cubic centimeter. The STP standard assumes a temperature of 32 degrees Fahrenheit and 0.987 standard atmosphere.
Full Answer >Aluminum has a density of 2.7 grams per milliliter. An element in the boron group, aluminum is a very light metal, but it is dense enough to sink in water. It is the third most abundant element in the Earth’s crust and is the most abundant metal overall.
