1) If the reference range for serum Ca2+ is 8.5—10.5 mg/dL, would a result of 2.3 mmol/L be within that range? How about a result of 4.8 mEq/L? 1 Eq = 1,000 mEq
2. One of the assays your laboratory routinely carries out requires 1.0 N H2504. You have in stock a bottle of concentrated sulfuric acid with a specific gravity of 1.84 and a purity of 97%. To achieve the target concentration of 1.0 N, how many milliliters of this acid must be diluted to a final volume of 100 mL?
3. Your laboratory uses an analytical instrument for lead (Pb) that requires calibration with four standard solutions of lead to be dissolved in 5% HNOB. To prepare one standard solution of 50.0 ug/ml, you mixed 5.0 mL of a sample with 95.0 mL of diluent (solvent). What was the concentration of manufacturer's solution in mg/dL before dilution?
