Molar solution, commonly called molarity, is the amount of amount of substance in a certain volume. Typically it is measured in moles per litre. A 1 molar solution means there is one mole of substance per one litre. This can also be called a one mole concentration of solution.

A 1 molar solution refers to a solution that contains 1 mole of solute dissolved in 1 liter of solvent. This concentration is commonly used in chemistry to describe the amount of a substance dissolved in a certain volume of solution. It is a way to express the concentration of a substance in a solution.
They're actually exactly the same in that neither of them exists.
Semi-molar refers to a solution that is halfway between being molar (having a concentration of 1 mole of solute per liter of solution) and being dilute. It typically refers to a solution where the concentration falls between 0.1 to 1 mole per liter.
To calculate the molarity for a millimolar (mM) solution, divide the number of millimoles of solute by the volume of the solution in liters. For a nanomolar (nM) solution, first convert nanomoles to moles, then divide by the volume in liters to obtain the molarity. Ensure to adjust the units accordingly to maintain consistency throughout the calculation.
A 1 molar solution of lactose would contain 342.30 grams of lactose per liter of solution. This concentration would give you one mole of lactose molecules in one liter of solution.
A one molar solution (1 M) contains one mole of solute dissolved in one liter of solvent. It is a way to express the concentration of a solution in terms of moles of solute per liter of solution.
