Hey there!
Using your density formula, D=M/V where D represents the density, M represents the mass, and V represents the volume, you can plug in your given values to find the density.
Knowing that your mass is 7.92 grams, and your volume is 3.25 mL, you can find the density by setting up this expression:
7.92/3.25
Now, simplify:
7.92/3.25
≈2.44
Therefore, your density of the object would be approximately 2.44 grams per mL.
Hope this helps and have a marvelous day! :)
