Grams to Moles Step 1 Find the number of gramsof the substance. You will know from the problem how many grams and what the substance is, for example, 12 g of water. Step 2 Find the molecular weight of each atom in the substance. The molecular weight is how much each molecule of the...
Add these values together foreach different atomin the molecule. This will give you themolecular massof the molecule. This is equal to the number of grams in one mole of the substance. Divide the number of grams of thesubstanceby the molecular mass. The answer will be thenumber of molesof...
Once you have both the molecular mass and physical weight of the compound, you can use a simple formula to calculate the number of moles present in the sample. Number of moles = Weight of compound (in grams) / molecular weight of compound In our example, the weight of NaCl is 100 grams...
