2. Find the number of moles of produced by the decomposition of 71.4g of 
:
3. Use the ideal gas equation to find the Volume of occupied by 1.65 moles of , at the temperature and pressure given by the problem:
Solving for V:
Converting the temperature from ◦C to K:
25◦C+273.15=298.15K
Replacing values:
V=36.7L of
