How do you make a 0.03 M H3AsO3 (150 mL) solution from NaAsO2? Please show calculations!

Therefore, for preparing 0.03 M solution of H3ASO3
weigh 0.5845 g of NaAsO2 and take out 257 microliter glacial acetic acid. Add both into a flask containing water. Now make the volume 150 ml to get the desired solution.
