calculate the mass defect for oxygen-16 given this data: mass of an oxygen-16 atom: 15.994914 amu mass of a proton: 1.00728 amu
o-na [289]
The answer is <span>0.132606 amu.</span>

The mass defect (Δm) is the total mass of protons and neutrons minus the mass of the atom. 
<span>mass of an oxygen-16 atom: 15.994914 amu
mass of a proton: 1.00728 amu
mass of a neutron: 1.00866 amu
</span>
An oxygen atom has 8 protons and 8 neutrons. Therefore:
Δm = 8 · 1.00728 + 8 · 1.00866 - <span>15.994914 = 8.05824 + 8.06928 - 15.994914 = 0.132606 amu

Which part of the iceberg displaces water equal in weight to the buoyant force?explain.
ohaa [14]

The iceberg has weight Wi = Mig and the buoyant force is equal to the weight of the displaced water, Ww = Mwg. Furthermore, since the iceberg is floating, its weight exactly balances the buoyant force:


Ww = Wi
Mwg = Mig
VwRhowg = ViRhoig
Vw = Rhoi/Rhow Vi

So, the fraction of ice underwater, Vw/Vi, is given by the ratio of densities Rhoi/Rhow=0.87. Over 87% of an iceberg's volume (and mass) is underwater. As you can see, the convenient definition of the gram gives us a quick way to see how much of a floating substance lies below the surface of fresh water: the fraction is equal to that substance's mass density in g/cm?.

Summary

<span>Archimede's Principle of bouyancy states that the bouyant force on an object is equal to the weight of the fluid displaced by that object.<span>The underwater fraction of a substance floating on water is given by that substance's mass density in g/cm3.</span></span>
