remove google account from android device if i sync a google account account to my android mobile, all my gmail, contacts will be synced with the google account and i can view my mobile contacts, photos from a web browser in pc by signing in my google account right. now my question is simple. if i remove my google account from my android mobile, will i still be able to view the already synced contacts and photos from a web browser in pc through internet?
Yes. 
If you have synced the account properly then you will be able to access all your content from browser even though you remove the account from android device.
