Mole & Avogadro Constant

Question 1

The Avogadro constant (NA or L) is the

Answer 1

number of particles equivalent to the relative atomic mass or molecular mass of a substance

amount of atoms in 12g of carbon 12

The Avogadro constant applies to atoms, molecules, ions and electrons

Question 2

Avogadro’s constant value is

Answer 2

The value of NA is 6.02 x 10(power)23 g mol-1

Question 3

avogrado constant units

Answer 3

g/mol -1

Question 4

The value of NA is 6.02 x 1023 g mol-1
The mass of a substance with this number of particles is called a

Answer 4

mole

Question 5

The mass of a substance containing the same number of fundamental units as there are atoms in exactly 12.00 g of 12C ?

Question 6

One mole of any element is equal to the

Answer 6

relative atomic mass of that element in grams
If you had one mole of carbon in your hand, that is 6.02 x 1023 atoms of carbon, you would have a mass of 12.00 g
One mole of water would have a mass of (2 x 1 + 16) = 18 g
