Question

A solid has a mass of 21.15 grams and a density of 1.688 g/mL. The solid is dropped into a graduated cylinder containing water with volume of 15.00 mL. When the solid is dropped into the graduated cylinder, the volume of the water goes up. Using the information given, calculate the final volume of the water in the graduated cylinder.

Answer 1

Mass of Solid = 21.15 g

Density of solid= 1.688 g/ml

Density = Mass/ Volume

So Volume = Mass/Density

= 21.15 g/1.688 g/ml = 12.53 ml

Since the solid is heavier than the water it will settle down in the graduated cylinder. Therefore, the volume mark of the graduated cylinder will increase equal to the volume of the solid.

Final Mark = volume of water + volume of solid

= 15.00 ml + 12.53 ml = 27.53 ml
