Common aluminum foil for household use is nearly pure aluminum. A box of this product at
a local supermarket is advertised as giving 75 ft°of material (in a roll 304 mm wide by 22.8 m
long). If the foil is 0.5 mil (12.7 µm) thick, calculate the number of atoms of aluminum in the
roll.
Given:
Density of Aluminum: p= 2.7 Mg/m³
Molar mass of Aluminum: MAI= 26.98 g/mol
Avogadro's Number: AN = 0.6203 (10)²ª
Choose the correct answer.
A material that has high bond energy and high bond stiffness is expected to have:
high Young’s modulus, high melting point, and low coefficient of thermal expansion
high Young’s modulus, low melting point, and high coefficient of thermal expansion
high Young’s modulus, high melting point, and high coefficient of thermal expansion
low Young’s modulus, low melting point, and high coefficient of thermal expansion
High tensile strength of a material is usually associated with its:
high electrical conductivity
high magnetic permeability
high hardness
none of the above
If a material exhibits a predominantly covalent bonding then the material is expected to have:
high hardness
high stiffness
high melting point
all of the above
