7

## What is the symbol for the prefix pico?

### p.

8

## What is the prefix for 10^-18?

### Atto.

9

## To convert from %w/v concentration to molarity, what do you do?

###
Determine concentration in g/L (remember 1% is 1g/100mL)

Then calculate the number of moles in a litre by using the gram value from the concentration above, and using n=m/M

10

## What is the prefix for 10^-9?

### Nano.

### 10^-2

12

## What is the symbol for the prefix Atto?

### a.

13

## When calculating weight per volume, what is an important detail to remember about the volume?

### The volume is measured in mL. 5% is 5 grams per 100 mL.

14

## What is the power of the prefix Atto?

### 10^-18

15

## What is the prefix for 10^-1?

### Deci.

16

## What is it important to remember when showing working in serial dilutions?

### List your dilution factor. If you dilute something by one power of 10, your dilution factor is 10^-1.

17

## What is the symbol for the prefix Mega?

### M.

18

## What is the prefix for 10^1?

### Deca.

19

## When you feel like you can only find two values for a beer's law question, where should you look for the third?

### The concentration of the standard may be in brackets after the absorbance.

20

## What is the symbol for the prefix Centi?

### c.

21

## What is the prefix for 10^3?

### Kilo.

22

## What is the prefix for 10^-10?

### Ångstrom.

23

## What is the power of the prefix Giga?

### 10^9

24

## What is the symbol for the prefix deca?

### da.

25

## What is the prefix for 10^-6?

### Micro.

26

## What is the prefix for 10^12?

### Tera.

27

## What is the symbol for the prefix Femto?

### f.

28

## What is the prefix for 10^9?

### Giga.

29

## What is the power of the prefix Deci?

### 10^-1

30

## What is the power of the prefix micro?

### 10^-6

31

## What is the prefix for 10^-2?

### Centi.

32

## What is the power of the prefix pico?

### 10^-12

33

## What is the symbol for Ångstrom?

### Å.

34

## If using Beer's Law to determine the concentration of a diluted solution, how do you determine the concentration of the concentrated solution?

### Use the dilution factor.

35

## What is the symbol for the prefix nano?

### n.

36

## What is the prefix for 10^-12?

### Pico.

37

## What is the symbol for the prefix Tera?

### T.

38

## Using two steps, how would you dilute a solution from a concentration of 5*10^9 to 1*10^6?

###
You know you need a 1:5000 dilution so you would use two factors of 5000.

To make it easy you would go from 5*10^9 to 5*10^6 and then from 5*10^6 to 1*10^6 by using a 1:1000 then 1:5 dilution.
