Hey there!:
To find the original sample population density, divide the conted colonies by the dilution factor and the inoculate:
= 73 / (10⁻⁴ * 0.1)
= 73*10⁵
Thus, the original sample's population density was 7.3*10⁶ or 73* 10⁵.
Hope this helps!
The population density of the original sample will be 73 × [tex]10^{5}[/tex] .
Population density would be a quantity of the type integer density; it would be a measuring of the population per unit area, even particularly per unit volume.
Calculation of population density
It is given that, counted colonies = 73
The dilution factor = 0.1 × [tex]10^{-4}[/tex]
population density = counted colonies / dilution factor = 73 / 0.1 × [tex]10^{-4}[/tex].
= 73 × [tex]10^{5}[/tex] .
Therefore, the population density will be 73 × [tex]10^{5}[/tex] .
