WebThink about your result. 0.25 L ( 250 mL) of the stock HNO 3 needs to be diluted with water to a final volume of 8.00 L. The dilution is by a factor of 32 to go from 16 M to 0.5 M. Exercise 13.7. 1. A 0.885 M solution of KBr with an initial volume of 76.5 mL has more water added until its concentration is 0.500 M. Webdilution factor x 1,000 (1000 µL = 1 mL). Example: 50 cells X 2 (dilution made in Trypan Blue) X 1,000 = 100,000/mL . NOTE: If an average is calculated per square out of the total squares counted less . then 10, multiply the average by 10. 4 (Example: average cells counted per square = 40 then the calculation would be 40 X 2 X 10,000 = 800,000/mL.
