Questions & Answers about ooku no gakusei wa mainichi nihongo o benkyoushimasu.

What does の do in 多くの学生?

の is linking 多く (many, much) to 学生 (students).

Structure:

• 多く = amount/quantity (many)
• 学生 = students
• 多くの学生 = many students

Here, の works like a connector that turns 多く into something that can directly modify the noun 学生. You can think of it as similar to of in English (many of the students), but in Japanese it is just a normal way to connect this kind of quantity word to a noun.
