pot odds..real beginner question

hey!

im a beginner and i need help [img]/images/graemlins/smile.gif[/img]

what are the pot odds for example a gutshot draw when only one card will come, cause i think im not gonna have the odds for calling the river to the turn.

the pot odds for two cards to come (turn and river) is 10.5-1..i will loose 10.5 times but profit the elevent time therefore i need the pot to lay over 10.5?

does someone have a link for these types of pot odds?

and what are the "standard" situations when i only will count the "one card to come" pot odds?

If i have 1 out to win the pot i need the pot to be 22.5-1 (turn and river) but i need the pot odds to be 45-1 if i onle gonna see one card? why is that?

thanks in advance and let the wine flow!
