Summary:
- The molar mass of any substance is the mass in grams of one mole of representative particles of that substance.
- In a laboratory situation, you may perform a reaction and produce a certain amount of a product which can be massed.
- It will often then be necessary to determine the number of moles of the product that was formed.
- A similar conversion factor can be used to convert from the mass of an substance to moles.
- The relatively small mass of product formed results in a small number ofmoles.
