#0.1667M#

Explanation:

  1. Take the formula mass of #Na_2CO_3#
  2. Find the number of moles by dividing the amount of #Na_2CO_3# as provided in the problem by its formulas mass;
  3. Compute the Molarity (M) using the formula;
    M=number of mol/L solution
  4. Make sure to cancel out units leaving only the desired unit
  5. Per calculation, M=0.1667 mol/L
