Number of moles of ammonia "(n)=1.366\\times 10^{-1}"
Volume of chamber"(V)=20 ml=20\\times10^{-3} L"
Temperature"(T)=299.1\\degree C=299.1+273=572.1K"
Predicted pressure using ideal gas equation:
"P_{id}V=nRT\\ (R=0.0821)"
"P_{id}\\times20\\times 10^{-3}=1.366\\times 10^{-1}\\times 0.0821\\times 572.1" "\\implies P_{id}=313.75\\ atm"
Predicted pressure using Van der Wall gas equation:
"(P +\\frac{an^2}{V^2})(V-nb)=nRT"
"(P+\\frac{4.17\\times 0.1366^2}{(20 \\times 10^{-3})^2})(20\\times 10^{-3}-0.1366\\times 0.0371)=" "0.1366 \\times 0.0821 \\times 572.1"
"P_{van}=235.14\\ atm"
