Because mass is not always the same for objects made from the same material. Just because an object has the same mass as another doesn’t mean they are the same material.
What is the difference between the two numbers? That is your answer
A mole is equal to 6.02x10^23, so one mole of H2O has 6.02x10^23 water molecules. To get how many of them are in 6 moles you need to multiple it by six:
(6.02x10^23)x6= 3.612x10^24
So, there’s 3.612x10^24 water molecules in 6 moles of water
Answer:
