In order to prepare a buffer solution of $\mathrm{pH}5.74$, sodium acetate is added to acetic acid. If the concentration of acetic acid in the buffer is $1.0 \mathrm{M},$ the concentration of sodium acetate in the buffer is ______$\mathrm{M}.$ (Round off to the Nearest Integer). $\left[\mathrm{Given}: \mathrm{pKa}\left(\text{acetic acid}\right)=4.74\right]$
