That would be called the quotient.
So, here you have to look at the periodic table and see what the molar mass of each molecule composing the water compound

its two hydrogen atom plus an oxygen molecule, making it about 18g per mol.
That said, looking at the mass, we have to ask ourselves, if a mol of water contains 18g of mass, how many moles do we have in 0.5g of water?
We just do a cross multiplication:
Hello!
First, let's write an equation for the problem.

Now, all you have to do is solve it.

=
16Each side is 16 meters. I hope this helps!
Answer:
