JEE Main 2025 — Solutions Question with Solution

Sea water, which can be considered as a 6 molar $(6\mathrm{M})$ solution of NaCl , has a density of $2\mathrm{g}{\mathrm{mL}}^{-1}$. The concentration of dissolved oxygen $\left({\mathrm{O}}_2\right)$ in sea water is 5.8 ppm . Then the concentration of dissolved oxygen $\left({\mathrm{O}}_2\right)$ in sea water, is $x\times 10^{-4}\mathrm{m}$.

$x=$ ___________. (Nearest integer)

Given: Molar mass of NaCl is $58.5\mathrm{g}{\mathrm{mol}}^{-1}$

Molar mass of ${\mathrm{O}}_2$ is $32\mathrm{g}{\mathrm{mol}}^{-1}$
