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 ...

Molar mass is the mass of one mole of a given substance, typically expressed in grams per mole (g/mol). It is a fundamental concept in chemistry that helps relate the mass of a substance to the amount ...

Copper (II) sulfate commonly exists as a pentahydrate, meaning it has five water molecules associated with each molecule of CuSO₄. To calculate the molar mass of CuSO₄·5H₂O, we need to include the ...

Aluminium can be obtained from aluminium ore (Al 2 O 3) by a process called electrolysis. Oxygen is also produced by this reaction. The balanced equation for this process is: \(\mathbf{2}Al_{2}O_{3}\, ...

You can work out the molecular formula from the empirical formula, if you know the relative mass formula (M r) of the compound. Add up the atomic masses of the atoms in the empirical formula. The ...
