How do you calculate alligation?
How alligation works?
- Step 1: Identify the data given. Higher concentration=10% w/v.
- Step 2: Convert all the data into similar form and units. Here all the concentration terms are expressed in % w/v terms, hence no need to convert the format.
- Step 3 : Apply alligation. Let’s indicate alligation ratio as H:L.
What kind of math is used in pharmacy technician?
On the job, you’ll use math concepts such as percentages, algebra, ratios and fractions to measure out medication, fill prescriptions and keep tabs on the pharmacy’s inventory. It’s important for you to understand math concepts in several measurement systems so customers get the correct amount of medication needed.
How is e value calculated in pharmacy?
First step is to memorize the equation.
- E= [58.5 x i] / [MW x 1.8] Got it? Good, then understand each value.
- 1 = 1 | 2 = 1.8 | 3 = 2.6 | 4 = 3.4 | 5 = 4.2. Next step is to understand what they actually means. The value provided above are dissociation ions.
- E= [58.5 x i] / [MW x 1.8] E= [58.5 x 3.4] / [150 x 1.8] = 0.737.
How to calculate alligation in Pharmacy Tech Review?
Set up a tic-tac-toe-style grid with your “want” in the middle and your “haves” on the left side with the higher percentage written in the upper-left corner and the lower percentage in the lower-left corner. Notice that you won’t use all the boxes. Our example has the unused boxes shaded out.
