Density = mass/volume
mass = volume * density
volume = mass/density
You were given both the volume and density of ethyl alcohol, and you're looking for the amount the mass of ethyl alcohol added to the graduated cylinder. So, plug in the numbers for mass:
30mL * 0.790g/mL = 23.7g ethyl alcohol
23.7g ethyl alcohol + 44.28g graduated cylinder = 67.98g
mass = volume * density
volume = mass/density
