i am given solid anhydrous sodium carbonate, i need to dissolve it with distilled water in order to carry out the titration, how do i work out the concentration of the solution from this formula? (say if the concentration of sodium carbonate is 0.1 mol/dm3 and adding 250cm3 of water)

✔ 最佳答案
you need to take 2.65g solid anhydrous sodium carbonate. then add 250cm3 water. after shaking, 0.1M sodium carbonate solution can be gained.the measurement is that first find the mole no. of solid sodium carbonate needed. then use the relative molecular mass to find out the weight needed.
