The mass of a deuterium nucleus 2 1 H is less than its component's masses. Calculate the binding energy in mev 3.521

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).

b. is the answer hoped i        

i believe the answer is three water molecules

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
