If the sample iluted and unstained, what is the cell density of the sample? Figure 2Explanation / Answer
Average Total number of cells in 4 squares = 150 + 145 +135 + 145 + 150 / 5 = 145
Number of cells/ mm2 = 145 X 25 = 3625 . In 1mm2 there are 25 small square are there so we should multiply that.
Number of cells/ mm3 = 3625 X 10 = 36250. 10mm is the distance between cover slip and hemocytometer.
Number of cells/ cm3 = 36250. X 103 103 is the volume
Number of cells/ cm3 = 3.625. X 107
