Question

1.06g of sodium carbonate is dissolved in 200ml of water. calculate morality?​

Answer 1

Answer:

your answer is

The dissociation equilibrium is Na2CO3⇋2Na++CO32−.

The molar concentration of sodium carbonate is 106 g/mol1.06 g×250 mL1000 mL×1 L=0.04 M.

This is also equal to the molar concentration of carbonate ion.

The molar concentration of sodium ion is equal to 2×0.04 M=0.08 M=8×10−2M.
