Which one should you use?
When used as an adverb meaning 'a lot', mucho is invariable and never changes. However, when it functions as a determiner or adjective meaning 'much' or 'many', it must change its form to match the noun it describes.

How does it change in a sentence?
As a determiner, mucho must agree in gender and number with the noun it modifies. Use mucho for masculine singular nouns, mucha for feminine singular nouns, muchos for masculine plural or mixed-gender groups (meaning 'many') and muchas for feminine plural nouns (meaning 'many'). When acting as an adverb meaning 'to a great extent', the form remains mucho regardless of the subject or verb.
How do you pronounce it?
/ˈmutʃo/
What mistakes should you avoid?
Avoid using the invariable form mucho for everything. While it stays the same as an adverb, you must change the gender and number when it describes a noun. For example, say muchas personas instead of mucho personas.
