3.1.2.2 The Mole And The Avagadro Constant

Question 1

What is a mole?

Answer 1

The amount of substance is measured using a unit called the mole.

Question 2

What is Avogadro constant?

Answer 2

6.02 x 10^23 (moles, atoms, electrons etc)

Question 3

Calculating the number of particles?

Answer 3

Number of particles = Avogadro Constant x Number of moles

Question 4

How to calculate moles of a substance using mass?

Answer 4

Moles = GRAMS/RAMS

Question 5

How to calculate moles using concentration?

Answer 5

Moles = Concentration X Volume(cm^3)/1000

Moles = Concentration X Volume(dm^3)
