The volume of a 12.4 g metal pellet is measured by water displacement. it is added to a graduated cylinder filled with water, and the level rises from 10.00 ml to 13.65 ml. what is the density of the metal?

                3.39 g.mL⁻¹ or 3.39 g.cm⁻³

Solution:

Data Given:

                             Mass of Pellet  =  12.4 g

                             Volume of Pellet  =  13.65 mL - 10.00 mL  =  3.65 mL

                             Density  =  ?

Formula Used,

                             Density  =  Mass ÷ Volume

Putting values,

                             Density  =  12.4 g ÷ 3.65 mL

                             Density =  3.39 g.mL⁻¹ or 3.39 g.cm⁻³

the answer is b. dilution
