Question

What are the final units when you have a mass (in grams), and then divide it by molar
mass

Answer 1

The final units are mol

Step-by-step explanation:

The units of molar mass are grams per mole, g/mol.

This means that when dividing mass by molar mass, the units of grams cancel each other, leaving only units of moles:

• Grams ÷ Grams/mol

Another way of writing that might help is as follows:

• 
  `(g)/((g)/(mol))`

Thus, the final units are moles.
