Word Usage
number - singular or plural?

Number is a collective noun that can take a singular or plural verb depending on how you use it. If you put the definite article the in front of number, you are stipulating one particular number, even if of and a series of things comes next. Therefore, you must use a singular verb with number preceded by "the": The number of lab coats available is limited. On the other hand, if you put the indefinite article a before number, you must use a plural verb: A number of lab coats are available.
