Consult the balanced reaction:

O₂ + 2 H₂ ⇄ 2 H₂O

which says you need twice as many moles of H₂ as O₂. So if 1.57 mol O₂ is available, then the reaction would consume 2 × 1.57 = 3.14 mol H₂.

The phrases from each of the sentences are most likely:

A participial phrase is the collection of words in a sentence which is made up of a participle, and a modifier. They perform various functions in a sentence such as being either the objects, or adding extra meaning to the word.

An infinitive phrase is a group of words which has an infinitive and also gives extra information about another word.

A Gerund phrase is a collection of words which has a gerund and another word which modifies a word. Some examples include: "Biking is such a fun sport".

An infinitive is a word that usually begins with a verb "to + extra word" for example, to eat, to walk, etc.
