A rock sample has a mass of 16 grams and a volume of 8 cubic centimeters. When the rock is cut in half what is the volume and density of each piece? Chemistry Measurement Density 1 Answer anor277 Oct 15, 2016 Answer: The density is constant; the volume is halved. Explanation: #rho="Mass"/"Volume"=(16*g)/(8*cm^-3)# #=# #??*g*cm^-3# And the volume of each piece is #??*cm^3#. Related questions How can density be used to identify substances?
