Is there a formula that says, if you ask n questions on a survey, you should give the survey to N people?

I am going to give a 53 item survey to a group of people. I know that there are formulas to determine how many people I should give it to, for probability and confidence; however, is there a formula that would indicate the correct number of people to give it to? This is about the number of items and the number of people. It's related to traditional statistical sample size, but it's about survey items and number of participants. Any help or reference material would be appreciated.
