A self-contained breathing apparatus used \[K{{O}_{2}}\] to convert \[C{{O}_{2}}\] and \[{{H}_{2}}O\] in exhaled air into oxygen and \[KHC{{O}_{3}}\] as shown in the equation \[K{{O}_{2}}+{{H}_{2}}O+C{{O}_{2}}\xrightarrow{\,}\,KHC{{O}_{3}}+{{O}_{2}}\]. How many molecules of \[{{O}_{2(g)}}\] will be produced from the 0.044 g of \[C{{O}_{2(g)}}\] that is exhaled in a typical breath?

• A. \[6\times {{10}^{20}}\]
• B. \[4.5\times {{10}^{20}}\]
• C. \[2.25\times {{10}^{21}}\]
• D. \[4.5\times {{10}^{22}}\]
