Answer: Given that 6.9 moles of carbon monoxide gas are

Here we have to calculate the pressure of the gas (in atm).

Step 1 of 2

Given:

Number of moles (n) of carbon monoxide gas present =6.9 moles

Volume \((\mathrm{V})=30.4 \mathrm{~L}\)

Temperature \((\mathrm{T})=62^{\circ} \mathrm{C}=273+62=335 \mathrm{~K}\)

According to ideal gas equation, it is known that

\(P V=n R T\)

Where \(\mathrm{P}=\) pressure in atm

\(\mathrm{V}=\) volume in \(\mathrm{L}\)

\(\mathrm{n}=\) number of moles

\(\mathrm{R}=\) gas constant \(=0.0821 \mathrm{~L} \operatorname{atm} \mathrm{mol}^{-1} \mathrm{~K}^{-1}\)

\(\mathrm{T}=\) temperature in kelvin.
