Calculate the sodium ion concentration when 70.0 mL of 3.0 M sodium carbonate is added to 30.0 mL of 1.0 M sodium bicarbonate.

Answer:- The sodium ion concentration when 70.0 mL of 3.0 M sodium carbonate is added to 30.0 mL of 1.0 M sodium bicarbonate is:

The molar mass of a material is referred as the mass of the substance contained in one mole of the substance. Therefore the concentration of sodium ions is 4.5M.
