First question:
How we can find Avogadro number if we know
density of Aluminum 2.7 g/mL
One mole of Al 26.98 g
radius of Al atom 143 picometers.. (1x10^-12)
Spherical density 74% (theoretical)
Cubic density 54 % (theoretical)
Second question: We need to find with of aluminum foil in atoms (how many atoms we can stack on each other to equal the with of aluminum foil
Given aluminum foil 744,5 cm^2
mass of foil 2.60 g
One mole of Al 26.98 g
density 2.7 g/mL
radius of 1 atom of Al 143 пикометров.. (1x10^-12)
Spherical density of Al 74% (theoretical)
Cubic density of Al 54 % (theoretical)
