d1*V1 = d2*V2
where d1 and V1 are the density and volume of object 1; d1 and V2 are the density and volume of the fluid
Then V2 = 0.14*V1
d1*V1 = d2*0.14*V1
d1 = d2*0.14
Look up the density of water at 0 degrees C (= d2). Solve for d1
b) d1*V1 = d2*V2
You know d1 from a. You can look up the the density of ethanol, d2.
% submerged = V2/V1 = d1/d2
