The absolute pressure within a $36\mathrm{.}0-$liter gas cylinder should not exceed $60\mathrm{.}0$atm. Suppose the cylinder contains $45\mathrm{.}0$mol of a gas. Use the $SRK$ equation of state to calculate the maximum permissible cylinder temperature if the gas is $($a$)$ ethane and $($b$)$ propane. Finally, calculate the values that would be predicted by the ideal gas equation of state.

$($Note: Please show your all calculations and add your excel spreadsheet in your homework!$)$
