How many moles of water are
in 1.23x1018 water molecules?
[? ]x10'?)

Answer 1

There are 2,04x10 e-6 moles of water in 1.23x10e18 molecules

Step-by-step explanation:

We use Avogadro's number, according to which in 1 mole of any substance there are 6,023 x 10 e23 particles (example: atoms, molecules). We calculate the number of moles according to the following simple three rule:

6,023 x 10 e23 molecules-----1 mol of water

1.23x10e18 molecules----x=

x=(1.23x10e18 molecules x1 mol of water)/6,023 x 10 e23 molecules

x=2,04x10 e-6 moles of water
