Question:
How many grams are in 2 moles of H₂O?
Answer:
One mole of H2O has a mass of (2*1 + 1*16 = 18g). We read the 1 and the 16 from the periodic table of the elements under “atomic weight” or “atomic mass”. I’ve taken the whole numbers from memory to keep it simple but you can read a more accurate value if you need a more accurate value from your periodic table.
So if one mole of H2O has a mass of 18g, then 2 moles will have a mass of 18*2 = 36g.
Note: * I am not responsible if you get it wrong, for you are the one who asked the question. *
