- What is the molarity of a solution that contains 18.7 g of KCl(MW=74.5) in 500 mL of water?
- 25 g of NaOH (MW = 40) is added to 0.5 L of water. What is themolarity of this solution if an additional 0.25 L of water is addedto this solution?
- How many grams of H2SO4 (MW = 98) are in750 mL of 3 N H2SO4?
- What is the normality of a solution that contains 280 g of NaOH(MW=40) in 2000 mL of solution?
- A serum potassium is 19.5 mg/100 mL. This value is equal to howmany mEq/L (MW = 39)?
You are given a series of 5 tubes, each of which contains 5 mLof saline. To the first tube is added 1 mL of serum, and a serialdilution using 1 mL is carried out in the remaining tubes.
- What is the dilution in the first tube?
- What is the final dilution in the third tube
- The third tube was run, and the triglyceride concentration was3 mg/dL. Give the triglyceride concentration in the 1sttube:
- What is the concentration of the original specimen?
- What result do you report out?
