Pre-Lab Questions:
1.
Imagine you are a guest speaker at a kindergarten class and you are asked to explain
Avogadro’s
number. What would you say and why?
Avogradro´s Number (Na) is a constant wich is equal to 6.022*10^23. Far any element
compound when 6.022 *10^23 paeticles are combined together it can be referred to 1
mole. Avogradro’s number helpt to relate number of particles to number of moles.
2.
Draw a diagram explaining the relationship between atoms, moles, and molecules. Insert
your
drawing with your handwritten name and access code clearly visible.
3. Why is Avogadro’s number referred to as a mole?
Avogadro's number is the number of carbon-12 atoms found in 12g of pure carbon-12. The
mole (also denoted as mol) represents the quantity of elementary particles/atoms/molecules.
So, 1 mol contains 6.02214 × 10
23
elementary entities of the substance. Generally we will get
moles from the formula
