One hundred (100) ml of raw goat's milk bought from a street vendor is added in bottle 1 which initially contains 900 ml diluent. The sample was serially diluted by transferring 10 ml each to the succeeding bottles 2, 3 and 4 all of which contain 90ml diluent. Calculate the final dilution in bottle 4 expressed in decimal number. (Attach a screenshot of your computations at the end of the assessment). 0.01 0.001 0.0001 0.00001 0.000001
