Calculate the volume occupied by 8.8 g of\[C{{O}_{2}}\] at 31.1C and 1 bar pressure \[(R=0.083\text{ }bar\text{ L}{{\text{K}}^{-1}}mo{{l}^{-1}})\]

Answer:

Information shadow: P = 1 bar, \[R=0.083\text{ }bar\text{ L}{{\text{K}}^{-1}}mo{{l}^{-1}}\] \[T=31.1+273=304.1K\] \[n=\frac{8.8}{44}=0.2\] \[V=?\] Problem solving strategy: Ideal gas equation can be used to calculate the volume of gas \[PV=nRT\] Working it out: \[1\times V=0.2\times 0.083\times 304.1\] \[V=5.048L\]
