A sealed cubical container $10\mathrm{.}0$ cm on a side contains a gas with five times Avogadro's number of krypton atoms at a temperature of $23\mathrm{.}0C.$

$($a$)$ Find the internal energy $($in J$)$ of the gas.

$$

J

$($b$)$ The total translational kinetic energy $($in J$)$ of the gas.

$$ J

$($c$)$ Calculate the average kinetic energy $($in J$)$ per atom.

$$ J

$($d$)$ Use $P=\frac{2}{3}(\frac{N}{V})(\frac{1}{2}\frac{m}{b}ar(v^2))$ to calculate the gas pressure $($in Pa $).$

$$ Pa

$($e$)$ Calculate the gas pressure $($in Pa $)$ using the ideal gas law $)=(nRT.$
