These cutlery spoons are also called a "teaspoon" and "tablespoon", but are not necessarily the same volume as measuring spoons with the same names: Cutlery spoons are not made to standard sizes and may hold 2.5~7.3 ml (50%~146% of 5 ml) for teaspoons [3] and 7~20 ml (47%~133% of 15 ml) for tablespoons. The difference in size can be dangerous ...
The result is that in dilute ideal solutions, the extent of boiling-point elevation is directly proportional to the molal concentration (amount of substance per mass) of the solution according to the equation: [2] ΔT b = K b · b c. where the boiling point elevation, is defined as T b (solution) − T b (pure solvent).
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 : [2]
In the United Kingdom, a pinch is traditionally 1 / 2 UK salt spoon, [5] the equivalence of 1 / 4 UK teaspoon. 1 / 2 UK salt spoon is an amount of space that can accommodate 15 British imperial minims ( 1 / 4 British imperial fluid drachm or 1 / 32 British imperial fluid ounce; about 14·41 US customary ...
A teaspoon (tsp.) is a small spoon that can be used to stir a cup of tea or coffee, or as a tool for measuring volume. [ 1 ] [ 2 ] The size of teaspoons ranges from about 2.5 to 7.3mL (about 0·088 to 0·257 imperial fluid ounce or 0·085 to 0·247 US fluid ounce).
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).

Here, 1 / f eq can have a fractional (non-integer) value. In precipitation reactions, the equivalence factor measures the number of ions which will precipitate in a given reaction. Here, 1 / f eq is an integer value. Normal concentration of an ionic solution is also related to conductivity (electrolytic) through the use of ...
