Alarge piece of jewelry has a mass of 132.6 g. a graduated cylinder initially contains 48.6 ml water. when the jewelry is submerged in the graduated cylinder, the total volume increases to 61.2 ml.
(a) determine the density of this piece of jewelry.
(b) assuming that the jewelry is made from only one suvstance, what substance is it likely to be? explain

a) The density of the jewelry will be  

b) The element is silver.

Explanation:

Density is defined as the mass contained per unit volume.

Given : Mass of jewelry = 132.6  grams

Volume of jewelry = volume of water displaced =

Putting in the values we get:

Thus density of the jewelry will be

As density is characteristic of a particular material , the material must be silver which has a density of 10.5 g/ml.

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

plz give brainliest

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
