A $10\mathrm{mg}$ effervescent tablet containing sodium bicarbonate and oxalic acid releases $0.25\mathrm{mL}$ of ${\mathrm{CO}}_2$ at $\mathrm{T}=298.15\mathrm{K}$ and $\mathrm{P}=1$ bar. If molar volume of ${\mathrm{CO}}_2$ is $25.0\mathrm{L}$ under such condition, what is the percentage of sodium bicarbonate in each tablet? [Molar mass of ${\mathrm{NaHCO}}_3=84\mathrm{g}{\mathrm{mol}}^{-1}]$
