342 grams of Lactose in 1 litre water or 34.2 grams in 100 mls.
They're actually exactly the same in that neither of them exists.
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.
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.
The term molar it refers a form to know the concentration of a solution, and it is equivalent to a molar unit in a litre of solvent 1 Molar (1M) = 1 mole (molecular weight from the structure you are interested in) / 1000 mL or 1 L. Milimolar is the thousandth part from a solution 1M

Find out the molecular weight of LactoseAdd that many grams of Lactose into a 1000ml volumetric flaskMake up the volume to 1000ml with waterYour 1 Molar solution of Lactose is ready---------------The molar mass of lactose is 342,3 g/mol; the solubility of lactose is 216 g/L at20 0C. Consequently you cannot prepare a molar solution of lactose.
1 molar solution of sugar water contains 342,3 g sucrose.
To make a 0.1 molar solution from a 1.0 molar solution, you would dilute the original solution by a factor of 10. For example, you could mix 1 part of the 1.0 molar solution with 9 parts of solvent (like water) to achieve a final concentration of 0.1 molar.

One liter of a one molar solution of NaOH in water contains 40g of NaOH. The quantity must be known.
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 make a 1 molar solution of glucose in 0.5 L of water, you would need to dissolve 90.1 grams of glucose powder. This is because the molar mass of glucose (C6H12O6) is approximately 180.2 g/mol, and for a 1 molar solution in 0.5 L of water, you would need 1 mole of glucose, which is 180.2 grams.

Only a compound has a molar mass not a solution.
To make a 1 molar solution of sodium azide, you would need to dissolve 65.01 g of sodium azide in water to make 1 liter of solution. Since you have 98 mg of sodium azide, you would need to add enough water to make a final volume of 1 liter to create the 1 molar solution.
