Saline (also known as saline solution) is a mixture of sodium chloride (salt) and water. [1] It has a number of uses in medicine including cleaning wounds, removal and storage of contact lenses, and help with dry eyes. [2] By injection into a vein, it is used to treat hypovolemia such as that from gastroenteritis and diabetic ketoacidosis.
Ringer was studying the beating of an isolated frog heart outside of the body. He hoped to identify the substances in blood that would allow the isolated heart to beat normally for a time. [ 19 ] The use of Ringer's original solution of inorganic salts slowly became more popular. [ 4 ]
For example, if there are 10 grams of salt (the solute) dissolved in 1 litre of water (the solvent), this solution has a certain salt concentration . If one adds 1 litre of water to this solution, the salt concentration is reduced. The diluted solution still contains 10 grams of salt (0.171 moles of NaCl).
Molar concentration or molarity is most commonly expressed in units of moles of solute per litre of solution. [1] For use in broader applications, it is defined as amount of substance of solute per unit volume of solution, or per unit volume available to the species, represented by lowercase c {\displaystyle c} : [ 2 ]
Historically, the mole was defined as the amount of substance in 12 grams of the carbon-12 isotope.As a consequence, the mass of one mole of a chemical compound, in grams, is numerically equal (for all practical purposes) to the mass of one molecule or formula unit of the compound, in daltons, and the molar mass of an isotope in grams per mole is approximately equal to the mass number ...
Previously, the court heard how the two women were attacked as they sat on the sand watching the full moon after lighting a fire. Ms Gray, a football coach from Poole, was pronounced dead at the ...
