If you add 43 of food in 350 ml water and dilution of 1: 6 is made then from this dilution 1: 90 is made and from this 1 ml is added to 60 ml of water then 0.1 ml from this last dilution is plated and after incubation 143 colonies are counted what is the total count per g of original sample

Solution:

DF = Initial dilution * Subsequent dilution * Amount Plated

Total Count Per g = * Colonies Counted

Initial dilution :

Subsequent dilution :

Amount Plated : 0.1

Colonies Counted : 143

DF =

DF=

DF =

Total Count Per g =

Total Count Per g =

16 kids because 2 times 8 equals 16

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
