Question

6. To determine the density of an irregularly shaped object, a student immersed the object in 21.2 mL of water in a graduated cylinder causing the level of the water to rise to 27.8 mL. If the object has a mass of 22.4 grams, what is the density of the object? Show all work.

Answer 1

\[Density=\frac{ mass }{ volume }\]
Know the mass and volume of the object?

Answer 2

so it is 22.4 /27.8
= density ?

Answer 4

The mass is right, but not the volume.
The object made the water rise to 27.8mL from 21.2mL
Since water density is 1.0 g/mL, then the amount the water went up from is the object volume.
So you subtract 27.8mL to 21.2mL to get the volume of th eobject
Your answer should be units g/mL

Answer 5

27.8-21.2=6.6

Answer 6

Yea, that is correct.

Answer 7

thanks you

Answer 8

No problem!
