1. How much NaOH(in grams) is reguired to prepare 0.2 M of 250 m! NaOH?(Naoh Ma= 40g/mol) 2. AWhite blood cell Suspension is dyed by Trypan Blue in 1:1 Ratio(Volume). 7 square is counted and the values are; Total Viable Cells: 168 Total Nonviable Cells:32 a.Percentage of Viable Cells: ? b.Average Number Of cells per square: ? ç.Dilution Factor:? d.Concentration (Vable Cells/ml): ? 3. Amniotic fluid(AF) was taken from the mother for the baby with suspected disease. Cells were counted in the amniotic fluid, the sample was placed on the Thoma slide. There were too many cells. Only 6 randomly counted on the second size of square areas; Number of cells in this AF sample found 97, 123, 113, 72,60, 105. (100 µl Sample Dilluted with 200 µl Trypan Blue.) a. Average of cells = ? b. Number of cells in 1 ml=? 0,025 0,05 1 mm Figure 1: Area Number 1: x10.000; Area Number 2: x250.000.
