5. Calculate the sodium ion concentration when 60.0 mL of 6.0 M sodium carbonate is added to 30.0 mL of 1.0 M sodium bicarbonate.
Molar Concentration or Molarity is defined as the moles of solute dissolved in one liter of solution.
<br>Molarity = moles of solute/liter of solution ----(1)
<br>Here we have 60ml of 6M sodium carbonate (Na2CO3) solution and 30ml 1M ...
Very clear solution which will enable you to do similar problems yourself.
