Excerpt from The Elements Chemical Arithmetic: A Short System of Elementary Qualitative Analysis A mass of matter is any portion of matter appreciable by the senses. A molecule 18 the smallest particle of matter into which a body can be divided without losing its identity or it is the smallest portion of matter which can exist by itself. An atom is a still smaller particle produced by the division of a molecule; or it is the smallest portion of matter that can go into combination. Examples. The sun and a grain of sand are masses of matter. The smallest particle of salt which can exist and which exhibits the properties of salt is a molecule. The minute particles of chlorine and sodium which com pose the molecule Oi salt are atoms. A mass is made up of molecules, and a molecule is com posed of atoms.

Excerpt from book: This rule can be simply expressed by the general proportion: ? M: m:: W: w, where M represents the molecular weight of the substance given, m the molecular weight of the substance asked, W the real mass of the substance given, and w the real mass of the substance asked; whence w 45. The Relations of Weight to Volume. 1. To find the volume occupied by a given weight of any gas. Rule. Divide the weight of the gas given by the weight of 1 liter; the quotient is the number of liters. 2. To find the weight of any given volume of gas. Rule. Multiply the number of liters of gas by the weight of 1 liter; the product is the weight of the given volume. Examples. 1. What volume is occupied by 6.08 grams of oxygen, the weight of 1 liter of oxygen being 1.43 grams ? 6.08 -=- 1 .43 = 4.25 liters. Ans. . 2. What is the weight of 25 liters of nitrogen gas, 1 liter weighing 1.26 grams ? 1.26 x 25 = 31.5 grams. Ans. 46. Density of Gases. The density of any gas ex presses how many times the gas is heavier than hydrogen. Knowing the density, the weight of 1 liter may readily be obtained by multiplying it by the weight of 1 liter ofhydrogen, O.OS9G grams, or 1 erith. The molecular weight of any/substance being the weight of 2 volumes of the substance in the state of gas, it is evident that its density in the state of gas may be obtained by dividing its molecular weight by 2. With few exceptions, the density of any elementary gas is expressed by the same number as its atomic weight, and that of any compound gus is expressed by the same number as half its molecular weight. Thus, oxygen, O = 10; density, 16; or 1 liter weighs 16 criths. Ammonia, NH3 = 17; density, 8.5; or 1 liter weighs 8.5 criths. 47. Relation of Gaseous Volume to Pressure. To calculate the chang..
