Molarity is the concentration of a solution in terms of the number of moles of the solute in 1 dm 3 (1 liter) of the solution. What are the units of molarity? The units of molarity are M or mol/L. A 1 ...

Both molarity and molality are measures of a chemical solution’s concentration. The primary difference between the two comes down to mass versus volume. The molality describes the moles of a solute in ...

The gram formula mass (GFM) of a substance is known as the mass of one mole. Relative atomic masses of selected elements can be found in the SQA Data Booklet.These can be used to calculate the gram ...

One mole contains the same number of particles as there are atoms in 12 g of carbon-12. As atoms and molecules are so small, the number of particles in a mole is very large. This number is: ...
