Avoid These Mistakes When Using Muchos

Using mucho instead of muchos with plural nouns

Incorrect: Hay mucho personas aquí.

Correct: Hay muchas personas aquí.

Before a plural noun, mucho must agree in both gender and number: muchos (m. pl.) or muchas (f. pl.). Mucho (singular) only works with uncountable nouns (mucho tiempo).

Confusing muchos with muy

Incorrect: Tengo muy amigos.

Correct: Tengo muchos amigos.

Muy means very and modifies adjectives/adverbs (muy alto). Muchos means many and modifies plural nouns. They are not interchangeable.
