Question

A piece of an unknown metal with a mass of 10.6 g place into a graduated cylinder containing water initially the graduated cylinder red 12.1 mL after addition of the solid it read 34.6 mL. what is the unknown solid

Answer 1

Mass = Density x Volume = 1 g/mL x 22.5 mL = 22.5 g

Therefore, the unknown solid has a mass of 22.5 g.

Step-by-step explanation:

To determine the unknown solid, we can use the concept of water displacement.

The initial volume of the water in the graduated cylinder is 12.1 mL, and after adding the solid, the volume increased to 34.6 mL.

To find the volume of the unknown solid, we subtract the initial volume from the final volume:

Volume of the unknown solid = Final volume - Initial volume = 34.6 mL - 12.1 mL = 22.5 mL

Since the density of water is 1 g/mL, we can assume that the unknown solid has the same density.

Now, we can calculate the mass of the unknown solid using the volume and density:

Mass = Density x Volume = 1 g/mL x 22.5 mL = 22.5 g
