Answer:
A mole is a unit of quantity it reprensents 6.022140 10^23 of something.
It is used a lot in chemistry, where molecules are so small that it becomes a unit of quantity because if would be awfully long to write those extremely high numbers.
Why 6.022140 x 10^23 ? Because there are 6.022140 x 10^23 atoms in 12 grams of Carbon-12.
So if I tell you that there are 6.022140 x 10^23 molecules present in 1 mole of water, I think you can find out by yourself how many moles are present in 5.7 x 10^23 molecules of water.
