How can I view my facebook email address?
From your last image, click General, it contains your basic information, like name, email, phone number, networks, and inactive account management person. 

The full path to this from the Facebook app is press the 3 line hamburger menu, scroll to the bottom section and find Account Settings, then General.

The way to access this information is exactly the same in the mobile web page. 

If they are not opening up, refresh the page or try a different browser. 

Also, if you have the Facebook app installed, go to Settings, Accounts, then Facebook, the email address associated with your account is right at the top of the page.
