millimoláris

Millimoláris refers to a unit of concentration in chemistry. It is a prefix that modifies the unit of molarity, which is moles per liter (mol/L). Specifically, "millimoláris" denotes one-thousandth of a mole per liter. The symbol for millimoláris is mM.

Molarity is a common way to express the concentration of a solute in a solution. A solution with a molarity of 1 M contains 1 mole of solute dissolved in 1 liter of solution. In contrast, a millimolar solution would contain 0.001 moles of solute per liter of solution. This unit is often used in biological and biochemical contexts where concentrations are typically much lower than those found in industrial chemical processes.

To convert between molarity and millimolarity, one can use the relationship 1 M = 1000 mM. Therefore, to convert a concentration from molarity to millimolarity, you multiply by 1000. Conversely, to convert from millimolarity to molarity, you divide by 1000. For example, a 0.05 M solution is equivalent to 50 mM. The use of millimolarity simplifies the notation for small concentrations, avoiding the use of many decimal places. It is a practical unit for everyday laboratory measurements and calculations.
