Dilutions Worksheet - Science Classroom Teacher Resources

5) How much water would I need to add to 500 mL of a 2.4 M KCl solution to make a 1.0 M solution? M1V1 = M2V2 (2.4 M)(500 mL) = (1.0 M) x x = 1200 mL 1200 mL will be the final volume of the solution. However, since there’s already 500 mL of solution present, you only need to add 700 mL of water to get 1200 mL as your final volume. The answer ...

Formulas for Calculating Medication Dosage

50 mg of nitroglycerin has been added to 500 mL of .9% NS. The order is to infuse the nitroglycerin at 5 mcg/min. The nurse needs to calculate how many mL/h the IV pump needs to be set at. First we have to calculate the mcg of the solution. If we have 50 mg in 500 mL, by moving our decimal point three spots to the right we have 50,000 mcg in ...
