$0.25\ M\ H_2SO_4$এর ঘনমাত্রা $ppm$এককে কত হবে?

$\begin{aligned} 0.25 M & =\frac{0.25 \mathrm{~mol}}{1 \mathrm{~L}} \\ & =\frac{0.25 \times 98 \mathrm{~g}}{1 \mathrm{~L}}\left[\mathrm{n}=\frac{\mathrm{w}}{\mathrm{M}}\right] \\ & =\frac{0.25 \times 98 \times 1000 \mathrm{mg}}{1 \mathrm{~L}} \\ & =24500 \mathrm{mg} / \mathrm{L} \\ & =24500 \mathrm{ppm}\end{aligned}$
