A chemist prepares a solution of sodium carbonate (Na2CO3) by measuring out 42.5 umol of sodium carbonate into a 150. mL volumetric flask and filling the flask to the mark with water. Calculate the concentration in mol/L of the chemist's sodium carbonate solution. Round your answer to 3 significant digits. mol ol. Х 5 ? A
