Arock weighing 32.0 g is placed in a graduated cylinder displacing the volume from 12.3 ml to 16.8 ml. what is density of the rock in grams /cubic centimeter?

               Density  =  7.11 g.cm⁻³

Solution:

Density is given as,

                               Density  =  Mass / Volume    (1)

Data Given;
                   Mass  =  32 g

                   Volume  =  16.8 mL - 12.3 mL  =  4.5 mL  =  4.5 cm³

Putting values in equation 1,

                               Density  =  32 g / 4.5 cm³

                               Density  =  7.11 g.cm⁻³

1. o2(g)as a product

So3 that’s what i think
