Question

A reaction produces 0.863 moles of H2O. How many molecules are produced?

Answer 1

Number of molecules = moles x 6.02 x 10^23 = 0.863 x  6.02 x 10^23 
                                                                         =    5.19 x 10^23 molecules.

Answer 2

To convert from moles to molecules, you multiply by Avogadro's constant.

0.863 moles H₂O * (6.022*10^23 molecules/1 mole) = 5.20*10^23 molecules H₂O

5.20*10^23 molecules of H₂O are produced.
