mol/L is different than mol/L/s.
mol/L (or Molarity): The concentration of a solution. How many moles of a certain compound would you find in a Liter of the liquid.
mol/L/s: Measures the change in concentration of a solution. This unit is used for kinetics experiments.

"Mol", or more commonly, "mol." is short for "Mole" which is 1x Avogadro's number, (which is 6.0221415 Ã 10^23).
This number is used to determine the amount of a substance in a sample, by grouping atoms.
The number was devised by calculating how many Carbon atoms there are in 12g of Carbon, and the answer is 12x(6.0221415 Ã10^23).
In Chemistry, this number is a standard and used to represent units of atoms. If you knew there was 3.01107075x10^23 atoms of an element, you would express that as a 1/2 or 0.5 mole.
The "/" sign between is a "divided by" sign.
Meaning, Moles divided by L, where L is liters.
mol/L is called the Molarity, and is another standard in Chemistry.
The mol/L/s is not a common, or an SI technical expression.
However, it mostly likely is derived from SI units, and that is: Moles divided by liters divided by seconds.
Meaning that you are to calculate the amount of moles per liter (ie Molarity) per second.
This could be used to calculate the speed of a reaction, and the value would be in mol./L/s.
Good luck with the Chem.

it means the amount of of mols of a substance disolved in a known quantity of liquid also known as molarity

it represent concentration of a given solution. It represent one mole of the solute in one litre of the solvent
Another name is molar(M).
