Using a dilution series is a way to transfer the very small volumes of original culture necessary to get countable colony forming units.   If you suspect your culture of bacteria has 59.62*10^9 cells per mL, how many mL of original culture would you want to end up on the plate to produce 68 cfu? Express your answer in scientific notation rounded to two decimal places. Eg.  0.01001 would be 1.00*10^-2 You must include trailing zeros 0.0000040001 would be reported as 4.00*10^-6 There must always be two decimal places, even if they are zeros Canvas expects one digit before the decimal point 0.40*10^-5 would be marked incorrect for 0.0000040001

Scientific Notation

We have to deal with quantities that are extremely large or very small. For example- I may have 6,500,000,000 red blood cells, or the diameter of an iron atom is 0.000000011 inches. Numbers with many zeros can be inexpedient to work with, so scientists use scientific notation. It represents very large numbers or very small numbers in a simple form. We know that whole numbers can be extended to infinity, but we cannot write such large numbers on paper. Numbers that present in millions of places after the decimal point need to be represented simply. Thus, it is difficult to represent a few numbers in their extended form. Therefore, we use scientific notation.
