<span>If it is known that at 60 °C and 745 torr UF₆ is present only as a gas then we can make the assumption that:

</span>(n/V) = P/RT = (745 torr)/(62.36 L-torr/mol•K)(337 K) = 0.0354 mol/L 
Therefore the density will be:
<span>
Density = (352.02 g/mol)(0.0354 mol/L)/(1000 cm³/L) = 0.0125 g/cm³

b. Write the half-reactions showing the oxidation and reduction reactions. Identify which is the oxidation reaction and which is the reduction reaction. (3 points)

oxidation half reaction: Al → Al3+ + 3e-

Reduction half reaction: Ag+ + e- → Ag

c. What is oxidized in the reaction? What is reduced? (2 points)

Aluminum is oxidized and silver is reduced

d. In this simple electrochemical cell, what functions as the anode? What is the cathode? (3 points)

In a simple electrochemical cell the electrode where oxidation takes place is the anode. And the electrode where reduction reaction happens is the cathode.

e. Is this a galvanic cell or electrolytic cell? Explain your answer. (2 points)

An electrolytic cell because the reaction converts electrical energy into chemical energy
