(a) Atoms are very small compared to objects on the macroscopic scale. The radius of a aluminum atom is 143
pm. What is this value in meters and in centimeters?
m
cm
(b) The mass of a single aluminum atom is 4.48×10-23 g. Suppose enough Al atoms were lined up like beads on
a string to span a distance of 37.7 cm (15 inches). How many atoms would be required?
atoms
What mass in grams of Al would be used?
g
Could you weigh out this amount of aluminum using a typical laboratory balance?
(c) Taking the density of aluminum metal to be 2.70 g/cm³, calculate the mass of metal needed to form a piece of
Al wire with the same length as the distance in b, but with a diameter of 1.00 mm. Hint: The volume of a cylinder is
n times its radius squared times its height. (V = n r² h)
How many aluminum atoms does this represent?

(a)
Carbon and iron are both elements. What is an element?
(b) A certain element has two naturally occurring isotopes.
The mass of one of the isotopes is 106.905 amu and its natural abundance is 51.60%.
The mass of the second isotope is 108.883 amu.
Calculate the average atomic mass
Write the chemical symbols of the isotopes
(c) An organic compound consists of carbon, hydrogen and sulfur only.
The percentage of carbon by mass in this compound wąs found to be 30.27%.
The complete combustion of 1.367 g this compound produces 1.765 g of sulfur dioxide
(SO2)
(i) Determine the empirical formula for this compound.
