How To: Convert grams to moles for chemistry
310tutoring shows viewers how to easily convert Grams to Moles for Chemistry. If you have 120 grams NaOH and we want this in moles we need a periodic table. Now, you need to figure out what the mass is of each individual element in NaOH. You need the mass of Na, O and H. Na mass is 23, O has 16 and H is 1. Add all of these up to get the molar mass of NaOH is 40 g/mol. Now use this to convert 120 g to moles. Now take 120 grams NaOh and multiply this by 1 mol NaOH/ 40 grams NaOH. You can cancel...
