Hi i need a simple answer and equation to this question,please. You are given a tube of contaminated water. Thenumber of bacteria in the tube istoo many to count. You prepare a tenfold dilutions in 5 tubes, so that tube#1 has 1:10 dilution, tube#2 has 1:100 dilution, tube #3 has 1:1000 dilution, tube #4 has 1:10,000 dilution and tube#5 has 1:100,000 dilution. The second tube has 210 cells and the third tube has 26 colonies. What is the number of bacteria per ml in the original sample?
