Much vs. Many
Much and many both express quantity, but they select different noun types. Much normally modifies singular uncountable nouns, while many modifies plural countable nouns; register also affects how often much appears in affirmative clauses.
Use much with singular uncountable nouns and many with plural countable nouns; in affirmative clauses, alternatives such as a lot of are often more natural in everyday English.
