Explanation:
According to Buoyance equation,
m =
where, m = true mass
m' = mass read from the balance = 17.320 g
= density of air = 0.0012 g/ml
= density of the balance = 7.5 g/ml
d = density of liquid octane = 0.7025 g/ml
Now, putting all the given values into the above formula and calculate the true mass as follows.
m =
=
=
= 17.317 g
Thus, we can conclude that the true mass of octane is 17.317 g.
