Let's start off with the balanced chemical equation:
Assuming the sodium carbonate is the limiting reagent, look at the coefficients of sodium carbonate and sodium chloride and use those as a ratio of sodium carbonate to sodium chloride: 1:2.
Since you have the required mass of NaCl, convert this to moles.
Assuming you know how to find the molar mass of NaCl:
Using the ratio, since 1 mole of sodium carbonate is required to produce 2 moles of sodium chloride, cross-multiply the ratios:
Therefore 1.027 moles of sodium carbonate is required to produce the required amount of sodium chloride. Convert to mass for your final answer:
Hope this helps :)
