Salary Expectations Question:

If you can't give a range and have to provide a single salary, choose the middle of your range, maybe even a little bit lower," she says. "You'd rather be lower than their target rate than over it."

In fact, negotiating for a bit more might work in your favor, since companies will see that you believe in yourself and have done enough research to know the value of your work.
