Answer:
one water molecule means H2O have a mass of (H=1)*2+(O=16)=18 atomic mass unit and as we know that one 1u = 1/Na that means mass of one water molecule is 18/Na =18/6.022 *10^23 ~ 3×10^-23

Answer:
The mass of water molecules is as follows :
Water have two components (H) hydrogen and (O) oxygen there in (H2O)
two molecules of Hydroden is present and one molecule of oxygen is present.
mass of 2 hydrogen molecules= 2*1
=2
mass of one molecule of oxygen =16
then total mass = mass of 2 hydrogen + mass of 1 oxygen
=2+16
=18g is mass of molecule of water
