NO!!!

Water is not a liquid per se.

Instead water occurs in three different states, from which only one is 
liquid.

Energy is also something else than mass, because the term 'energy' 
denotes a quantity in physics and this has a different meaning than 'mass'.

Mass is actually a measure for resistance against acceleration and 
measured in kg.

Energy is derived from the quantity work, which is defined as 
W=force*distance.

The units are Newtonmeter or Joule.

The quantity you erroneously call 'mass' is not measured in kg but in mol.

What you actually wanted to say, that is: matter is actually immaterial 
and a form of energy.

BUT: 'the amount of matter' is not measured in kg but in mol.
