Explanation:
To get the volume of tetrahydrofuran needed, what the student need to do is to apply mathematical calculations.
We know quite well that to obtain the volume of a substance, given the mass of the substance and the density of the substance is possible.
The volume of the substance is simply the mass of the substance divided by the density of the substance.
This is thus volume = mass/density
The mass given is the question is 60g while the density given is 0.889g/cm^3
The volume = 60/0.889 = 67.492cm^3
