calculate the mass of a substance when it is completely decomposed

sodium chloride is obtained when sodium carbonate is reacted with hydrochloric acid the equation for the reaction is; Na2CO3 = 2HCl ---> 2NaCl + CO2 + H20 Calculate the mass of sodium chloride that can be obtained when 53g of sodium carbonate is completely decomposed. (RAM = C=12, O=16, Na=23)
