JEE Main 2022 · 29 Jul · Shift 2, Chemistry question 81

'x' g of molecular oxygen (O$_2$) is mixed with 200 g of neon (Ne). The total pressure of the non-reactive mixture of O$_2$ and Ne in the cylinder is 25 bar. The partial pressure of Ne is 20 bar at the same temperature and volume. The value of 'x' is _______.

[Given: Molar mass of O$_2$ = 32 g mol$^{-1}$. Molar mass of Ne = 20 g mol$^{-1}$]
