An educated guess is called estimation
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!
A secondary alcohol has a hydroxyl group bonded to a disubstituted carbon bonded to one alkyl group carbon bonded to two alkyl groups carbon bonded to three alkyl groups aromatic carbon.
An alkene in which the doubly bonded carbons are bonded to a total of two carbon atoms, its a distributed alkene.
