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 >The density of the metal magnesium is 1.74 grams per cubic centimeters. Magnesium is a solid at room temperature and it belongs to Group 2 on the periodic table.
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 >The density of butane is 2.48 grams per cubic centimeter when the substance is at standard temperature and pressure conditions. The density is determined by dividing the mass in grams by the volume in cubic centimeters.
