Question

Calculate the number of molecules in `14.8` moles of water `("H"_2"O")` ?

Answer 1

heyyy!

so 1 mole of anything, literally anything, contains `6.022` x `10^23` particles. !

so accordingly, 14.8 moles of anything, (here, `H_2O`) contains
`14.8` x `6.022` x `10^23` molecules.
that's `89.1256` x `10^23` molecules of water.
