QJEEM22Ch21e2: JEE Main 2022 Chemistry - Class 11 JEEM22Ch21e2 Solution: 'x' g of molecular oxygen ( O 2 ) is mixed with 200   g of …

'x' g of molecular oxygen $$\left({\mathrm{O}}_2\right)$$ is mixed with $$200\mathrm{g}$$ of neon (Ne). The total pressure of the non-reactive mixture of $${\mathrm{O}}_2$$ 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 $${\mathrm{O}}_2=32\mathrm{g}{\mathrm{mol}}^{-1}$$.

Molar mass of $$\mathrm{Ne}=20\mathrm{g}{\mathrm{mol}}^{-1}$$]
