Question:

The concentration of hemoglobin in blood is roughly 15.0g/100.mL of solution. Assume that a solution contains 15.0g of hemoglobin dissolved in water to make 100.mL of the solution and that the osmotic pressure of this solution is found to be 0.0500 atm at 25oC. What is the molecular mass of hemoglobin? (The osmotic pressure of a 1 m solution at 25o C is 24.45 atm)

Answer:

π = (nRT) / V or MM= (dRT) / π so MM = (15/0.1) (0.08206) (298) / 0.05 = 73,400 g/mol

Question:

Show that any function f may be expressed as the sum of an even and an odd functions.

Khanh N.

Answer:

Let us write f(x) as follows f(x) = (1 / 2) f(x) + (1 / 2) f(x) + (1 / 2) f(-x) - (1 / 2) f(-x) = (1 / 2) (f(x) + f(-x)) + (1 / 2)(f(x) - f(-x)) Let . g(x) = (1 / 2) (f(x) + f(-x)) Check that g(x) is even g(-x) = (1 / 2) (f(-x) + f(x)) = g(x) Let . h(x) = (1 / 2) (f(x) - f(-x)) Check that h(x) is odd h(-x) = (1 / 2) (f(-x) - f(x)) = - (1 / 2) (f(x) - f(-x)) = - h(x)
