To change from moles to grams easily you can use the mnemonic "when you change from moles to grams you Mole-tiply". Here is how you do it:
Write down the number of moles you want to convert to grams.
Look up the molar mass of the substance you are working with. This can be found on the periodic table, and it is usually expressed in grams per mole.
Multiply the number of moles by the molar mass. This will give you the number of grams.
Note if you are going from grams to moles you do the reverse, you divide by the molar mass of the compound.

For example, let's say you have 2 moles of carbon dioxide (CO2) and you want to convert it to grams Because we are going from moles to grams we Mole-tiply:
Write down 2 moles of CO2.
Look up the molar mass of CO2, which is 44.01 grams per mole.
Multiply 2 moles by 44.01 grams per mole to get 88.02 grams of CO2.
So, when you change from moles to grams, you Mole-tiply by the molar mass. It's a simple and useful mnemonic to remember when converting between these units.
