Grammar question, please help.?

Both are correct:

Chocolate can be a "count noun" or a "non-count noun". Count nouns are countable. A 1-lb box of Russell Stover candy may have 50 chocolates (pieces of chocolate).

As a non-count noun, chocolate refers to the product itself (like rice, flour, sugar, etc).

Hi Phantom,

'chocolate' does not normally have a plural, but you can use 'chocolates' for these boxes of small chocolates. So both sentences are correct, though a) implies a general meaning (I'll have any kind of chocolate) while b) points to the specific little chocolates in the box in front of you.

I want some chocolate. is correct

There grammatically correct, but the sentence you choose depends on, do you want one chocolate, or more than 1 chocolate.

The first one is correct. Chocolate is spelled the same, singular or plural.
