How do you prepare 100mM of magnesium chloride?

Answer 1

100 mM means 0.1 M , So weight out 0.1 x 95.211 g = 9.52 g

Answer 2

To prepare a 100mM magnesium chloride solution, you would need to first calculate the molecular weight of magnesium chloride (95.21 g/mol for MgCl2). Then, weigh out the appropriate amount of magnesium chloride hexahydrate (MgCl2·6H2O) or anhydrous magnesium chloride to dissolve in a specific volume of water to achieve a final concentration of 100mM. Finally, ensure the solution is thoroughly mixed before use.
