The sentence is correct grammatically. Some state verbs can't be formed in the passive, but others can be put in the passive. For example: He is known to me. You are loved by us. This house is owned by me.
The word contain in the sentence presented is also a state verb that is usually followed by the preposition in/within in the passive, especially when you want to say that something is included to be part of a book. document. report or speech, etc. For Example:
The information you want is contained in this report.
Different new sections are contained in the bill.
You're correct, the sentence in passive voice is:
Two liters are contained in the bottle.
(are instead of is because "liters" is plural)
