Question 1

Strength of concentrated fluid. Index

Answer 1

C

Question 2

Volume in ounces of concentrated fluid/ounces in bottle.

Answer 2

V

Question 3

Strength of diluted fluid (Index in tank).

Answer 3

C1

Question 4

Volume in ounce of diluted fluid (Amount in tank).

Answer 4

V1

Question 5

C X V = C1 X V1

Answer 5

Equation for finding amounts of concentrated or diluted fluid.

Question 6

Know ounces in the arterial fluid and the index (strength of the fluid). Multiply the ounces with the index (convert the percentage for index to a decimal).
(Ounces times index)

Answer 6

How to Find the Amount of Ounces of HCHO in a Bottle of Arterial Fluid.

Question 7

Subtract the Index from 100 and multiply that number by the ounces.

Answer 7

Checking Answer (for ounces times index)

Question 8

If we have a 16 ounce bottle of 30 index fluid, it will contain _____ ounces of formaldehyde.

Answer 8

4.8 ounces

Question 9

If 8 ounces of 30 index fluid is used to make one gallon of solution, the index of the diluted solution will be _____.

Answer 9

1.9 Index

.30 X 8= C1 X 128
2.4 = C1 X 128
2.4/128 = C1
C1 = 1.9 Index

Question 10

How much of a 25 index fluid will it take to make 3 gallons of a 1.5 index injection solution?

Answer 10

23.04 Ounces

.25 X V = .015 X 384
.25 X V = 5.76
V = 5.76/.25
V = 23.04 ounces

Question 11

What is the strength of the concentrated fluid, when 32 ounces (2 bottles) of arterial fluid are used to make a total of 2.5 gallons resulting in a final solution strength of 1.5% diluted.

Answer 11

15 Index

C X 32 = .015 X 320
C X 32 = 4.8
C = 4.8/32
C = 15 Index

Question 12

What would the volume of injection be if one bottle of 25 index fluid is used to create 1.5 index strength of injection in primary dilution?

Answer 12

2.08 Gallons

One bottle = 16oz
.25 X 16 = .015 X V1
4 = .015 X V1
4/.015 = V1
V1 = 267 ounces
V1 = 2.08 gallons
