Numeracy

Question 1

mass

Answer 1

how much of a substance there is
in kg, mg, Mg

Question 2

other unit for mass

Answer 2

Dalton
1 Da= 1.66 x 10^-24
mass of one proton or neutron
used to describe the mass/size of molecules

Question 3

amount of substance

Answer 3

how many copies of an entity there are
units are mols
1 mol= 6.02214076 x 10^23

Question 4

volume

Answer 4

quantitative measures of how much 3d space a substance occupies
1m^3 = 1000ml
can also use pints and gallons

Question 5

1 gallon is how many pints

Answer 5

8

Question 6

1 pint is how many ml

Answer 6

568 ml

Question 7

1 gallon is how many litres

Answer 7

4.546

Question 8

concentration

Answer 8

quantitative measure of how much one substance is within a known quantity of usually another substance
how much per unit volume is mg/ml
how many per unit volume is mol/L = molarity

Question 9

how to express mass per unit volume

Answer 9

mg/ml
g/L
ng/ml

Question 10

molarity

Answer 10

moles per unit volume
1 mol/L = 1 M

Question 11

1% w/v

Answer 11

1g mass in 100ml total volume

Question 12

1% v/w

Answer 12

1g mass in 100g total mass

Question 13

1% v/v

Answer 13

1ml volume in 100ml total volume

Question 14

ppm

Answer 14

parts per million
so 1ppm w/v is 1g mass in 1,000,000 ml total volume

Question 15

moles equation

Answer 15

mass (g) divided by molar weight (g/mol)

Question 16

concentration equation (ug/ml)

Answer 16

mass (ug) divided by volume (ml)

Question 17

molarity (M or mol/L)

Answer 17

moles (mol) divided by volume (L)

Question 18

kilo

Answer 18

k
x 10^3

Question 19

deci

Answer 19

d
x 10^-1

Question 20

centi

Answer 20

c
x 10^-2

Question 21

milli

Answer 21

m
x 10^-3

Question 22

micro

Answer 22

μ
x 10^-6

Question 23

nano

Answer 23

n
x 10^-9

Question 24

pico

Answer 24

p
x 10^-12

Question 25

femto

Answer 25

f
x 10^-15

Question 26

dilution factor equation

Answer 26

new volume divided by old volume

Question 27

new concentration after a dilution

Answer 27

use the c1 v1= c2 v2 equation
ensure to adjust the units

if using a stock solution then divide the target dosage by the stock

Question 28

body surface area calculation

Answer 28

can use a nomogram where you draw line from height and weight to determine the body surface area
or use the equation:
BSA: W^0.425 x H^0.725 x 0.007184

ensure to sense-check incase value is too high or too low depending on the other values that have been given
