1. A blood serum sample is analyzed and found to contain 102.5 µg Ca*/mL serum. The density of the serum is 1053 kg/m³; AW Ca = 40.08. What is the Ca+ concentration, in terms of (a) molarity ? (b) meq Ca?* /L serum? (c) ppm Ca+2 by wt? 2. How many mL of a 0.250M KCI solution must be diluted to 1.000 L so that the diluted solution (density = 1.00 g/mL ) is 400 ppm K* by weight ? (MW KCI = 74.55; AW K = 39.10)

How many grams of KCl will be undissolved when 50g of KCl is dissolved in 100g of water at 20.0oC?

The total concentration of dissolved particles in blood is 0.30 M. An intravenous (IV) solution must be isotonic with blood, which means it must have the same concentration. To relieve dehydration, a patient is given 150mL/h of IV glucose(C₆H1₁₂O₆) = 180.156 g/mol) for 1.5 hours. Calculate the following:       a) How much (in mL) of IV glucose did the patient receive?       b.) What is the concentration (in % w/v) of IV glucose administered to the patient?       c.) If 0.25-mL blood sample was obtained from a patient and was diluted to 2.00 mL using saline solution, what is the diluted concentration of the blood sample in molarity?
