so much and so many
The difference
The difference between so much and so many is the same as between much and many (see here). So much is used with singular (uncountable) nouns; so many is used with plurals.
- I had never seen so much food in my life.
- She had so many children that she didn’t know what to do. (not
… so much children …)
We use so, not so much, to modify adjectives and adverbs (see here).
- You’re so beautiful. (not
You’re so much beautiful.)
But so much is used before comparatives (see here).
- She’s so much more beautiful now.
so much/many without a noun
We can drop a noun after so much/many, if the meaning is clear.
- I can’t eat all that meat – there’s so much!
- I was expecting a few phone calls, but not so many.
so much as an adverb
So much can be used as an adverb.

Special structures with so much

In negative and if-clauses, so much as can be used to mean ‘even’.
