Expert Solution
Step 1

Given,

Volume of water = 10 ml 

Final Volume(after addition of metal)  = 10.80 ml .

Mass of metal sample =5.27 g 

As we know,

Volume of metal = Final Volume- Volume of water

     = 10.80ml -10ml

      =0.80ml 

So density of metal,

Density = mass/Volume

           =5.27g/0.80ml
