Final answer:
The final water level, after a solid with a mass of 21.278g and a density of 2.48 g/cc is added into the water with initial volume of 23.3 ml, is 31.88 ml.
Step-by-step explanation:
The question is asking us to find the final water level when a solid is submerged in it. We know that the volume of the displaced liquid is equal to the volume of the solid submerged. We use this principle together with the formula for the volume of a solid, which is mass/density.
First, we calculate the volume of the solid using the formula mass/density. So, the volume of the solid is 21.278g / 2.48 g/cc = 8.58 cc, or 8.58 mL since 1 cc = 1 mL. Now, when we put the solid into the water, it will displace water equivalent to its volume, causing the water level to rise.
So, the final water level is the initial volume of the water plus the volume of the displaced water (which is equal to the volume of the solid). Hence, the final water level is 23.3 ml (the initial volume of the water) + 8.58 ml (volume of the solid) = 31.88 ml.
