A solid with a mass of 19.3 g is added to a graduated cylinder filled with water to the 25.0 mL mark.After the solid sinks to the bottom,the water level is at 35.8 mL.What is the density of the solid?

Question

Quizplus · Accepted Answer

The volume of the solid can be found by subtracting the initial volume of water (25.0 mL) from the final volume of water with the solid submerged (35.8 mL): 
volume of solid = final volume - initial volume
volume of solid = 35.8 mL - 25.0 mL
volume of solid = 10.8 mL

We can use the formula for density to find the density of the solid:
density = mass / volume

We know the mass of the solid is 19.3 g and we just found the volume of the solid to be 10.8 mL. 
density = 19.3 g / 10.8 mL = 1.79 g/mL

Therefore, the answer is C, 1.79 g/mL, which is the density of the solid.
