Step 1

To calculate the moles of carbon dioxide of given sample using the following gas law formula. help_outlineImage TranscriptionclosePV=nRT here, pressure(P)-1.06 atm volume(V) 8.48 L temperature(T)=27'C or 300.15K ideal gas costant(R)=0.08206 L.atm/ mol.K number of moles(n)=? fullscreen
Step 2

Let us take x is the moles of carbon dioxide, then the total moles of the givne sample as follows:

Step 3
