"Tem um pouco de água na garrafa."

Translation: There is a little water in the bottle.

[NetziKat]

"There is a little bit of water in the bottle" will also be correct?

[kcmurphy]

It should be.

[akeean]

"It has a bit of water in the bottle" so bad? Didn't pass :-/

[TaliaKG]

That sentence does not sound natural in English. "There is a bit of water in the bottle" would work.
