Answer:
a structural formula
Explanation:
A structural formula simply shows the arrangement of atoms on a compound or molecule.
They are mostly used in representing hydrocarbons.
Through a structural formula we can give name to a compound.
For example, the compound given is called Propane, an aliphatic hydrocarbon with 3-carbon atoms.
The bond relationship connecting the species are also shown in this designation.
Answer:
Explanation:
Mean of observation of A = 87.63
Mean of observation of B = 87.06
Mean of observation of C=87.76
So reading of B is closest to true volume hence his result is most accurate. Reading of C is least accurate.
As far as precision of measurement is concerned, it depends upon measuring instrument. From the reading it appears that the measuring instrument is the same because the no of significant figure of the reading is same ( three) . Hence their reading are equally precise.
