Which is correct?
 
Hi everybody,
Please help me to choose the correct from of the following verb?
Forty percent of the world �s oxygen is or are produced there.

is produced !

oxygen is uncountable, and so is its 40%, so it must be singular.

Have a look at this:


percent - singular or plural?

If percent stands alone without a subsequent prepositional phrase, you can use a singular or a plural verb with it: Sixty percent is accounted for;Sixty percent are accounted for. If a prepositional phrase following percent contains a noun or pronoun object regarded as a unit or a whole, use a singular verb: Sixty percent of the electorate is accounted for. If the object of the preposition in such a phrase is regarded as a number of people or things, use a plural verb: Sixty percent of the votes are accounted for
