Chapter 3, Question 18
(a) Show that the formula mass of NaCl is 58.442 +/- 0.006 g/mol.
(b) To prepare a solution of NaCl, you weigh out 2.634 (+/- 0.002) g and dissolve it in a volumetric flask whose volume is 100.00 (+/- 0.08) mL. Express the molarity of the solution along with its uncertainty, with an appropriate number of digits.

Beginning with the Weizsäcker semi-empirical mass formula, show
that the minimum in a mass parabola occurs at a value of atomic
number, Zmin, given by
Note: The Weizsäcker semi-empirical mass formula for the binding
energy, B, of a nucleus is where A is the atomic mass number of the
nucleus and Z is the atomic number of the nucleus. Hint: Although
atomic number, Z, only takes integer values, assume it is a
continuous variable for the purpose of this exercise....

mass)NaCl,7%(by mass)MgCl2)3% by mass)KCl and 85%(by
mass)water(H2O). What are the average molecular weight of the
solution(salt plus water). What is the average molecular weight of
the water free of solution( that is , the average molecular weight
of the NaCL,MgCL2, and KCl components of the solution)? Finally, if
the specific gravity of the solution (salt and water) is 1.14, what
are the concentrations of each of the salts(NaCl,MgCl2,KCl) in

Chapter 3 question from Global Communication)
At the end of chapter 3, Hamelink reminds us that
international/global communication is often characterized by
continuity (permanence) and change. With this in mind, how has the
development of communication fundamentally changed our perception
of time and space? Provide examples to support your opinion (use
the textbook, news, journal articles--makes sure to cite
properly)

-----------------------------------------------------------------------------------------------------
capacity is just 5
1. push 6 numbers on the stack
2. catch the overflow error in a catch block
3. pop one element, which means your capacity is now down to
4
4. push the element that was rejected earlier
5. verify your entire stack by popping to show the new
numbers.
