3A. Determine the Molarity of the Sodium ion in a solution of Na2SO4.10H20 if you add 3.041 grams to a final volume of 150 ml. Add 3.041 g of Na2SO4.10H20 in a beaker pour upto 150ml of water to achieve 0.063 Molar. Calculation Na2SO4.10H20 MW = 322.03g/mol Grams = 3.041 g Vf = 150ml = 0.15L M= mols of solute/ L of solution (3.041g/1) (1mol/ 332.2g) = 0.00915mol Na2SO4.10H20 0.00915mol N22SO4.10H20/ .15l= 0.061 M 2 Na = 2*0.061mol/L = 0.126 mol/L Answer the question below Make a 1:100 solution of Na2SO4.10H20 in 100 ml of water from your previous solution.

1. "Diffusion" sounds slow, but on the scale of a cell it is very fast. The average instantaneous velocity of a particle in solution is v= (kT/m)", where k = 1.38 X 101 g cm?/K sec², T= temperature in K, m = mass in g/molecule. A) Calculate the instantaneous velocity of a molecule of glucose and a molecule of myoglobin (a protein), at 37°C [molecular mass for glucose = 180 g/mol; molecular mass for myoglobin = 15,000 g/mol].
