Question 16

An analytical chemist determines that a waste runoff sample contains sodium carbonate, $Na2CO3\text{Na}_2\text{CO}_3$ , at a concentration of 18.55 g dm^-3.

Calculate the concentration of this sodium carbonate solution in $dm−3\text{mol dm}^{-3}$ .

(Relative formula mass, $M_r$ : $Na2CO3=106\text{Na}_2\text{CO}_3 = 106$ )
