With uncountable nouns:

A great/good deal of and a large/huge amount of are used with uncountable nouns.

• I have spent a great deal of time thinking of the design.
• You have got rid of a large amount of old clothing.
• We use a huge amount of paper in the office every day.

• No amount of love would heal the hatred she felt.
• I had a certain amount of respect for him: he was a good footballer and a good ambassador for his country.

We can also use amount as a verb, as in amount to, and again this describes the counting or measuring of something:

• When you added everything up, his total expenditure on this project amounted to £9,950.
• I don’t think the talks in Helsinki will amount to very much.

With countable nouns:

A large/great number of and a great/good many (An extremely large number (of persons or things) ) are used before plurals, and the verb that follows is plural. An extremely large number (of persons or things)

• Despite the instructions, a large number of people didn’t know what to do.

We use number to describe how many, and often we do not know exactly how many there are. This is one of the defining aspects of a number of. Number is countable and can be applied to both animate and inanimate items.

• a large number of cows were infected.
• There are a number of reasons why I can’t marry you.
• A number of people were injured in the explosion.
• I had warned her not to go there any number of times, but she wouldn’t listen.

We use plenty of as a quantifier before both countable and uncountable nouns to mean ‘a lot’, ‘a large quantity’: 

Don’t worry there are plenty of options.

A quantity of can be followed by a countable noun or an uncountable noun. We often talk about large or small quantities of something. It is usually applied to inanimate objects.

We often contrast quantity with quality:
