In order to prepare a buffer solution of 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).
[Given: \( \mathrm{p}K_a \) (acetic acid) = \( 4.74 \)]
