A graduated cylinder was filled with water to the 15.0 ml mark and weighed on a balance. It's mass was 27.35 g. An object made of silver was placed in the cylinder and completely submerged in the water. The water level rose to 18.3ml. When reweighed the cylinder,water and silver object had a total mass of 62.0g.
Calculate the density of silver.
:
Mass of the silver:
62 - 27.35 = 34.65 g
:
Volume of the silver:
18.3 - 15.0 = 3.3 ml of water displaced by the silver
:
Convert ml to cu/cm;
we know that; 1 liter = 10^3 cu/cm
1 ml = 1 cm^3
therefore: 3.3 ml = 3.3 cm^3
:
Density is defined as the ratio of Mass to Volume often given as, grams/cm^3:
D =
D = 10.5 is the density of silver
