Asample of metal has a mass of 34.65 g. when placed in a graduated cylinder containing 20 ml of water, the water level rises to 23.3 ml. which of the following metals is the sample made from: silver, which has a density of 10.5 g/cm3; tin, which has a density of 7.28 g/cm3; or titanium, which has a density of 4.5 g/cm3?

- The sample is made from silver, which has a density of .

Solution:- Mass of the metal is 34.65 gram. Volume of water in the graduated cylinder is 20 mL. When the metal is placed in the cylinder filled with water, the water level rises to 23.3 mL.

So, the volume of the metal = 23.3 mL - 20mL = 3.3 mL

Now, we have the mass and volume of the metal, so it's density could easily be calculated by using the density formula:

since,

So, density =

Hence, the sample is made from silver, which has a density of .

r just means there's a number of carbon in teh chain. for example rcooh means that after x number of carbon, the chain ends with cooh.
