Final answer:
Without the initial volume of water or the volume displacement caused by the rock, it is impossible to determine the final volume of water after the rock is dropped in. When resolving a similar problem involving jewelry submerged in water, we can calculate the jewelry's density using the mass and volume displacement.
Step-by-step explanation:
To calculate the final volume of water in the graduated cylinder after a rock is dropped into it, one would have to know the initial volume of water and then measure the new, higher volume level after the rock is submerged. However, since the problem does not provide a starting volume or the volume displacement caused by the rock, we cannot accurately determine the final volume (V2).
According to the information provided, in a separate scenario, a piece of jewelry with a mass of 132.6 g is submerged in 48.6 mL of water, which raises the level to 61.2 mL. To find out the density of the jewelry, the change in volume is calculated as follows: ΔV = Vfinal - Vinitial = 61.2 mL - 48.6 mL = 12.6 mL. The density (ρ) can be found using the formula: ρ = mass/volume, therefore: ρ = 132.6 g / 12.6 mL = 10.52 g/mL.
