WebLiter. Definition: A liter (symbol: L) is a unit of volume that is accepted for use with the International System of Units (SI) but is technically not an SI unit. History/origin: There was a point from 1901 to 1964 when a liter was defined as the volume of one kilogram of pure water under the conditions of maximum density at atmospheric pressure. However, due … WebAnswer (1 of 2): I interpret your question this way. There are 1.41 x 10^24 silicon atoms. How many moles of silicon atoms are there? A mole of any atom includes a total number of 6.02 x 10^23 atoms. Therefore, the number of moles of silicon atoms = (1.41 x 10^24) / (6.02 x 10^23) = 2.34 mol
