I found a calculation to determine the number of BitCoins earned per hash:

=(86400*Hash*25)/(2^32*Difficulty)

86400 = Seconds in a Day
25 = Bitcoins in a block
2^32 = Shares to find a block

How do I apply this formula to another coin? 
Do all coins list the number of shares to find a block? 
How does inventor of an alternate coin normally list the number of shares to find a block?
Do all coins list the number of coins per block or do I need to find a block to determine it?
Where is difficulty normally listed for a coin?
Does this formula change when applied to Scrypt coins or other algorithm coins?

Thanks in advance for your assistance,
