An amagat is a practical unit of number density. Although it can be applied to any substance at any conditions, it is defined as the number of ideal gas molecules per unit volume at 1 atm (= 101.325 kPa) and 0 °C (= 273.15 K).〔 〕 It is named after Émile Amagat, who also has Amagat's law named after him. The abbreviated form of amagat is "amg." ==Definition== Number density in amg, denoted here by , is defined as :, where ''n''0 = 1 amg = 2.686 7805 m−3 = 44.615 036 mol/m3 is the Loschmidt constant. In practice, number density of an ideal gas at pressure ''P'' and temperature ''T'' can be calculated as〔In this formula, absolute units of pressure and temperature, relative to vacuum and absolute zero, must be used.〕 :, where ''T''0 = 273.15 K and ''p''0 = 101.325 kPa. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「amagat」の詳細全文を読む スポンサード リンク
