Counting Molecules

Question 0

Moles

Answer 0

Element in periodic table is assigned an atomic mass
Known as relative mass
6.022 x 1023
Identical number of mass components

Question 1

Moles

Answer 1

System uses the mole
Number of molecules
Convention was adapted by expressing atomic mass
Elements in terms of atomic mass units

Question 2

Moles

Answer 2

One enzyme molecule reacts with 1 substrate

Question 3

Mm

Answer 3

Relative atomic masses if all the elements
Compound and converting to grams
Grams are molar mass
Dalton - an alternative the cumbersome name of atomic mass unit

Question 4

Moles and molariry

Answer 4

Mile refers to the amount of substance
Molariry refers to the conc
Mole is a measure of the amount of substance

Question 5

Cont

Answer 5

Conc= no of moles\ volume = c

Less than one 1 mole conc

Question 6

Dilutions

Answer 6

Simple dilution - desired conc

Serial dilution - amplifies the dilution factor quickly

Question 7

Summing up

Answer 7

Mass of molecule is the masses of the atoms

Relative molecular mass one mole compared to one 12th of the mass

Question 8

Dilutions

Answer 8

Molariry = m(%solution)x10/ mr
