What is the power of the prefix Deca?

10^1.

2

What is the prefix for 10^-3?

Milli.

3

What is the symbol for the prefix Kilo?

k.

4

What is the power of the prefix Mega?

10^6

5

What is the power of the prefix Kilo?

10^3

6

What is the power of the prefix nano?

10^-9

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.

11

What is the power of the prefix Centi?

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.

39

What is the symbol for the prefix Deci?

d.

40

What is the symbol for the prefix Giga?
