Counting bacteria?

Calculate the bacterial count per ml of sample of a pure culture after serial dilution.





Im lost i dont understand how to do this...

Counting bacteria?
100000/10ml = 10000/Xml





10000 = 100000X





1 =Xml





Which means you would dilute down to 1ml to have 10000 bacteria. Then you would use a hemocytometer or Coulter counter to count the bacteria.
