Question 19

What is a diluent?

Answer 19

is an inert substance that does not have a concentration. The diluent adds either volume or mass to the preparation.

Question 20

How can concentration can be expressed?

Answer 20

In percent, ratio strength, and fractions

Question 21

What is express in weight/weight?w/w%)

Answer 21

number of grams of solute dissolved in 100g of final product.

Question 22

What is express in weight/ volume?(w/v%

Answer 22

number of grams of solute dissolved in 100 ml of solution

Question 23

What is express in volume/ volume?(v/v%):

Answer 23

number of milliliters of solute dissolved in 100ml of solution

Question 24

What is ratio strength?

Answer 24

used to designate the concentration of weak solutions or liquid preparations. Ex= 1:1000

Question 25

What is express in solids in solids?

Answer 25

1 g of solid in 1000g of solution preparation

Question 26

What is express in solids in liquids?

Answer 26

1g of solid in 1000ml of solution.

Question 27

What is express in volumes in volumes?

Answer 27

1ml of solute in 1000ml of solution

Question 28

What is the third method that use mg/ml?

Answer 28

fractions

Question 29

How to find percentage to mg/ml

Answer 29

multiply the percentage strength by 10

ex: 5% (w/v) = 5mg/ml x10 = 50mg/ml

Question 30

How to find ratio to mg/ml

Answer 30

divide the ratio by 1000

ex:1:20,000 (w/v) = 20,000/1000 = 1mg/20ml

Question 31

How to get product strength expressed as (g/L)

Answer 31

convert the numerator to milligram and divide by the number of milliliters in the denominator
1g/100ml=1000mg/100ml

Question 32

What does IW stand for?

Answer 32

initial weight

Question 33

What does IV stand for?

Answer 33

initial volume

Question 34

What does IS stand for?

Answer 34

initial concentration

Question 35

What does FW stand for?

Answer 35

final weight

Question 36

What does FV stand for?

Answer 36

final volume

Question 37

What does FS stand for?

Answer 37

final concentration

Question 38

What is the formula to calculate the dilution process?

Answer 38

(IS)(IW or IV) = (FS)(FW or FV)

Question 39

How can the amount of diluent can be calculated?

Answer 39

(FW or FV)-(IW or IV)= amount of diluent

Question 40

What should you remember when using strength?

Answer 40

1. give ratio strength is given, convert to percentage strength
2. reduce to the lowest term before performing the calculation
3. initial strength always greater than the final strength
4. Final weight is greater than the initial weight.

Question 41

What is alligation?

Answer 41

method to calculate the number of parts of ingredients when they are mixed to prepare a mixture of desire strength.
