QUESTION
How would you calculate the density of methanol (##CH_3OH##)?
You would actually measure the mass of an accurately measured volume of methanol at a given temperature.
And of course, ##rho,"density"## ##=## ##"Mass"/"Volume"##.
For methanol at ##298K##, ##rho=0.792*g*cm^-3##.
Methanol is immiscible with petroleum ether, ##rho=0.653*g*cm^-3##. Would methanol float or sink on/in pet. ether?
