Question

a piece of wax floats on the brine. what fraction of its volume is immersed? (density of wax =0.95g/cm3, density of brine =1.1g/cm3)

Answer 1

weight (or mass) of the wax piece = d_wax * V_wax
weight of brine liquid displaced = d_brine * V_immersed

Both weights are equal as per Archimedes principle.
So   V_immersed / V_wax = d_wax / d_brine = 0.95 / 1.1
       = 0.8636
