How can I check my Bitcoin gold balance and how can I find the address which contains my free coins?
( I don't want to import the private key into a wallet and just I want to check my balance)

i just checked with my bitcoin address and it works. you just paste your bitcoin address in its search bar and it automatically converts your BTG address to BTG address and also shows you your balance.
What is the difference between bitcoin cash and Bitcoin gold which causes Bitcoin cash address is same as Bitcoin address, but Bitcoin gold address is different from that?
one of the issues that these kinds of fork cause is that people send coins to wrong addresses. for example sending BTC to BCH address or vice versa. that causes a lot of headache for recovering your funds. you may even lose it if the address belonged to a service like a gambling site for example. they won't credit you back.
so they change the format so that BTG address is invalid in BTC and BTC is invalid in BTG. it is just the address format though, nothing changed about private keys.
