a large piece of jewelry has a mass of 132.6 g. a graduated cylinder initially contains 48.6 ml water. when the jewelry is subme
Tresset [83]

The jewelry is submerged in the graduated cylinder, the total volume increased to 61.2 ml mass of the water in the graduated cylinder is 128.5 gram.

<h3>What is density?</h3>

Density is a amount of a substance per unit area of the volume of the mass and it is the ratio of mass and the volume unit is centimeter cube.

The density of the substance = mass / volume

substituting the value in the equation,

Density = 132.6 / 48.6 = 2.1 centimeter cube.

         mass = density  volume

         mass = 2.1  61.2

         mass = 128.5 gram.

Therefore,  mass of the water in the graduated cylinder is 128.5 gram if jewelry is submerged in the graduated cylinder, the total volume increased to 61.2 ml.
