Embalming Fluid Dilution Calculation

If you use 16 oz of 30 index fluid, how many gallons of a 2.5% solution will you have

1 1/2 gallons

What percentage dilute solution is created by adding 32 ounces of a 28 index fluid in enough water to make 4 gallons of solution

1.75 index

1 bottle of fluid

16 ounces

How much of a 16 index fluid will it take to make 2 gallons of a 1.5% solution

24 oz

V

Amount of liquid in the bottle (ounces)

C'

Concentration of strength of arterial solution (percent)

Accessory Chemicals

When accessory chemicals are mentioned in the problem, they will not be used in the above equation. Only ARTERIAL FLUID is used in the above calculation. (Because arterial fluid is the only determining factor of strength of solution)

Reminders

1 gallon = 128 ounces 1 bottle of fluid = 16 ounces Ideal sterilization achieved at 2 - 3% strength of solution

If you use 8 oz of 16 index fluid to one gallon of water, what would be the index of your solution

1.0%

The amount of arterial fluid necessary to make one gallon of solution at 2% strength using a 20 index fluid is

12.8 oz

1 gallon

128 ounces

What index fluid must you use to have 2 gallons of diluted fluid with a strength of 1% if you use 16 oz of concentrated fluid

16

Ideal solution achieved at

2 - 3% strength of solution

Formula for question above done differently

25% x X = 2% x 128 ounces 25x X 2% x 128 ounces 25 divided by 256 ounces = 10.24 ounces

If the solute is 28 index and you wish the solution to be 3 gallons of 3%, how many ounces of solute will you need

41.1 ounces

If you used 2 bottles of arterial fluid to make 3 1/2 gallons of a 3% solution, what would the index of the arterial fluid be

42 index

V'

Amount of total solution in the tank (ounces)

Amount of Water Calculations

As an exception to the rule above, accessory chemicals are used in calculation total volume of solution in the tank. Total capacity of tank - total ounces of all chemicals = total amount of water used (ounces)

Embalming Fluid Dilution Calculation

C x V = C' x V'

Prepare 1 gallon of a 2% arterial solution using a 25 index fluid

C x V = C' x V' (Index) x (Volume of FLUID) = (Strength of SOLUTION) x (total volume) C: Concentration in the bottle: 25% index fluid V: Volume in the bottle: V (it's what we need to solve for) C': Concentration in the tank: 2% V': Volume in the tank: 1 gallon, 128 ounces 25% x V = 2% x 128 ounces 25%V / 25% = V 256% / 25% = 10.24 ounces V = 10.24 ounces

C

Concentration of formaldehyde in the bottle (Index: strength of an embalming fluid, indicated by the number of grams of pure formaldehyde gas dissolved in 100 mL of water. Index usually refers to a percentage; an embalming fluid with an index of 25 usually contains 25% formaldehyde gas)
