Percent yield calculator which can help you apply this to actual experiments. This project started with as a molar mass calculator for chemical reactions. Note that the calculator assumes a pure substance - if you'reĪware of dilution or impurities, make appropriate adjustments for the molarity of a given substance. The calculator takes the elemental composition of the compound and weighs the elements to get an The molar mass of a chemical compound based on the compound's empirical formula. Need to know the atomic mass of a potassium bromide molecule? Our molar mass calculator uses the periodic table and the chemical formula to solve for Molarity ( M) is a useful concentration unit for many applications in chemistry.Solving for the atomic mass of potassium bromide (KBr) Solute concentrations are often described with qualitative terms such as dilute (of relatively low concentration) and concentrated (of relatively high concentration).Ĭoncentrations may be quantitatively assessed using a wide variety of measurement units, each convenient for particular applications. A solution in which water is the solvent is called an aqueous solution.Ī solute is a component of a solution that is typically present at a much lower concentration than the solvent. Solutions in which water is the solvent are, of course, very common on our planet. This component is called the solvent and may be viewed as the medium in which the other components are dispersed, or dissolved. Often, though not always, a solution contains one component with a concentration that is significantly greater than that of all other components. The relative amount of a given solution component is known as its concentration. We will explore a more thorough treatment of solution properties in the chapter on solutions and colloids, but here we will introduce some of the basic properties of solutions. Solutions occur frequently in nature and have also been implemented in many forms of manmade technology. We have previously defined solutions as homogeneous mixtures, meaning that the composition of the mixture (and therefore its properties) is uniform throughout its entire volume. In this section, we will describe one of the most common ways in which the relative compositions of mixtures may be quantified. The relative amount of sugar in a beverage determines its sweetness (see ). The relative amount of the active ingredient in a medicine determines its effectiveness in achieving the desired pharmacological effect. The relative amounts of iron, carbon, nickel, and other elements in steel (a mixture known as an “alloy”) determine its physical strength and resistance to corrosion. The relative amount of oxygen in a planet’s atmosphere determines its ability to sustain aerobic life. Similar to a pure substance, the relative composition of a mixture plays an important role in determining its properties. However, mixtures-samples of matter containing two or more substances physically combined-are more commonly encountered in nature than are pure substances. In preceding sections, we focused on the composition of substances: samples of matter that contain only one type of element or compound.
