Edward Meza · Answer 1

The volume of the water that is filled in the graduated cylinder is calculated by dividing the given mass of the water by its density. That is,

V = m / D

where V is volume, m is mass, and D is density. Substituting the known values,

V = (75.595 grams) / (0.99707 g/mL) = 75.82 mL

Answer: 75.82 mL
