Learn Turkish: Mola ne zaman? - When is the break?

In Turkish, ne means "what" and zaman means "time". Put together, ne zaman literally translates to "what time," which is the standard way to ask "when".

Where is the word for "is" in Mola ne zaman?

There isn't one! In simple sentences like this, Turkish usually leaves out the "to be" verb (am/is/are) for the "he/she/it" form. The meaning "is" is simply understood from the context.

Why does mola (the break) come before the question word?

Turkish usually puts the subject of the sentence first. Question words like ne zaman are typically placed right before the verb. Since the verb "is" is invisible here, ne zaman just goes at the end.

How would I answer this question with a time, like "at half past three"?

To answer "at" a specific time, you add a locative suffix (-de/-da/-te/-ta) to the time. For exact hours, it attaches to the number: Saat üçte (At three o'clock). For half hours, it attaches to the word for half: Saat üç buçukta (At half past three).
