The temperature of $\displaystyle 1$ mole of an ideal monoatomic gas is increased by $\displaystyle 50$°C at constant pressure. The total heat added and change in internal energy are $\displaystyle E_1$ and $\displaystyle E_2$, respectively. If $\displaystyle \frac{E_1}{E_2}=\frac{x}{9}$ then the value of x is $\displaystyle \_\_\_\_$
