The total number of neutrons present in 54 ml(millilitre) water?

i want full procedure

Then we want to see some effort. This is no homework forum. Hint, assume density is 1 g/ml

Hint: Don't forget to account for isotopic abundances. Most hydrogen atoms have no neutrons, but deuterium and tritium do.

I doubt that's going to have a significant impact on the result.

It depends on how many significant digits he wants to keep. If not many then yes, I agree. I assumed that as this seems to be homework the OPer would be required to account for such or the problem would be somewhat trivial. If we are counting neutrons here then lets count neutrons.

 

I remember similar problems from highschool chemistry. Besides, its good practice. If the example were to involve lets say Boron, it would most certainly make a difference as the isotopic abundance split between ¹⁰B and ¹¹B is about 20%/80% respectively.
