What does mol L−1 mean? - Chemistry Stack Exchange
Dec 19, 2016 · The units are mole per liter. $\mathrm{mol \times L^{-1}}$ is more conveniently written $\mathrm{mol/L}$. This set of units is referred to as molarity , and is a common measure of concentration for a solute dissolved in a solvent.
Molar concentration - Wikipedia
In chemistry, the most commonly used unit for molarity is the number of moles per liter, having the unit symbol mol/L or mol/dm 3 in SI units. A solution with a concentration of 1 mol/L is said to be 1 molar, commonly designated as 1 M or 1 M.
What does the ‘−1’ superscript mean in units?
Oct 22, 2014 · The -1 means "per" unit. So your first example mol/L-1 /s-1 is not correct - it would actually be written as mol L-1 s-1, OR mol/(L s). It is also sometimes written as mol/L/s, but the double division is ambiguous and should be avoided unless parentheses are used. If it were mol L-1 s-2, this would mean moles per litre per second per second.
Molarity Calculator
Molar mass is the mass of one mole of a substance, typically expressed in grams per mole (g/mol). The formula to calculate molarity using molecular weight is, M = m MW V = m MW×V. Where: M is the molarity (mol/L), m is the mass of the solute (g), MW is the molecular weight of the solute (g/mol), V is the volume of the solution (L).

Dec 10, 2023 · An aqueous solution that contains 1 mol (342 g) of sucrose in enough water to give a final volume of 1.00 L has a sucrose concentration of 1.00 mol/L or 1.00 M. In chemical notation, square brackets around the name or formula of the solute represent the molar concentration of a solute.

Jun 19, 2023 · The units moles per liter (mol liter –1) or moles per cubic decimeter (mol dm –3) are used to express molar concentration. They are equivalent (since 1 dm –3 = 1 liter). If a pure substance is soluble in water, it is easy to prepare a solution of known concentration.
Convert moles to liters and liters to moles - Online calculators
The calculator below uses the formula to convert liters to moles and to convert moles to liters, where is 22.413962. This online calculator converts moles to liters of gas and liters of gas to moles at STP (standard temperature and pressure).

Molar mass can then be used as a conversion factor to convert amounts in moles to amounts in grams. It is important to remember that “mol” in this expression refers to moles of solute and that “L” refers to liters of solution. For example, if you have 1.5 mol of NaCl dissolved in 0.500 L of solution, its molarity is
Molarity: Definition, Formula, Application, & Solved Problems
The SI unit of molarity is moles per liter (mol/L). Therefore, molarity measures the number of moles of solute in one liter of solution. Example: If 2 moles of solute are dissolved in 0.5 liters of solution, the molarity is: M = 2 mol/0.5 L = 4 mol/L . A solution with a concentration of 1 mol/L is called 1 molar solution or 1 M.
Molarity - ChemTeam
"A one molar solution is prepared by adding one mole of solute to sufficient water to make one liter of solution." The most typical molarity problem looks like this: What is the molarity of _____ grams of [a chemical] dissolved in _____ mL (or L) of solution.
