Is there a picture? If not then it’s probably precipitate
Answer:
2.95 g / mL
Explanation:
For this problem, we will simply use the equation that density is equivalent to mass over volume. We are given the mass of the object and the initial and final volumes of water in the cylinder. Thus we can find the density as such:
Density = Mass / ( Final Volume - Initial Volume )
Density = 3.689 g / ( 8.54 mL - 7.29 mL )
Density = 3.689 g / ( 1.25 mL )
Density = 2.9512 g / mL
Hence, the density of the object is 2.9512 g / mL.
Cheers.
