The molar mass of a solute can be calculated using the following equation:
Molar Mass (M) = (Mass of Solute (g)) / (Number of Moles of Solute (mol))
Here’s a breakdown of the equation:
- Mass of Solute (g): This is the mass of the solute measured in grams.
- Number of Moles of Solute (mol): This is the amount of solute measured in moles.
To find the molar mass, you simply divide the mass of the solute by the number of moles of the solute. This gives you the mass of one mole of the solute, which is its molar mass.
For example, if you have 58.44 grams of sodium chloride (NaCl) and you know that this amount corresponds to 1 mole of NaCl, then the molar mass of NaCl would be:
Molar Mass of NaCl = 58.44 g / 1 mol = 58.44 g/mol
This equation is fundamental in chemistry for determining the molar mass of any solute.
