why is it vannet and not vannen? can anyone explain to me please? thank you very much
Because "vann" is intetkjønn (neuter) noun. Therefore et vann - a water / vannet - the water.
'vann' is a neuter noun.
It's showing me vatnet not vannet. Why?
"vatn" is also water in Bokmål.
Duolingo just showed another alternate answer for you.
