how much downloads can i get from admob campaigns

hello, i dont know anything about advertising, i want to know how many downloads can i get from spending 50$ on admob campaign (1 cent per click) if i do good targeting and use text ads (double click)? the reason i want to advertise is to get my app to a country’s new free apps

I also have same question but just to clarify another question – Does your app contains admob banner ads?

no it doesn’t, i dont like their ecpm and payment terms
