Answer:

The answer is " $\bold{83.8^{\circ} \ C}$ ".

Explanation:

Formula for calculating the mass in He:

$\to m = \frac{PV}{RT}\\$

$= \frac{500 \times 1}{ 2.0769 \times (40 + 273)}\\\\ = \frac{500 }{ 2.0769 \times 313}\\\\ = \frac{500 }{ 650.0697}\\\\= 0.76914 \ Kg$

Formula for calculating the mass in $N_2$ :

$\to m = \frac{PV}{RT}\\$

$= \frac{500 \times 1}{ 0.2968 \times (120+ 273)}\\\\ = \frac{500 }{ 0.2968 \times 393}\\\\ = \frac{500 }{ 116.6424}\\\\= 4.2866\ Kg$

by using the temperature balancing the equation:

$T' = \frac{mcT (He) + mcT ( N_2 )}{ mc (He) + mc ( N_2)}$

$= \frac{0.76914 \times 3.1156 \times 313 + 4.2866 \times 0.743 \times393}{ 0.76914 \times 3.1156 + 4.2866 \times 0.743} \\\\ = 357 \ \ K \approx 83.8^{\circ} \ C$
