Tom Holland mixes two beakers he found in the lab; beaker X with beaker Y to make beaker Z. Tom Holland knows that a new substance is made if the density of Z is different than X and Y. The density of X and Y was the actually same, 10g/mL. Complete the chart below to find the density of Z (hint: Density = mass/volume). Then determine if Z is a new substance or not.
Density = Mass / Volume
