Calculate the sodium ion concentration when 50.0 mL of 2.0 M sodium carbonate is added to 100.0 mL of 3.0 M sodium bicarbonate.

asked by Will
  1. mols Na2CO3 = M x L = ?
    mols Na^+ = twice that since there are two Na ions in 1 molecule of Na2CO3.
    mols NaHCO3 = M x L = ?
    Total Na = mols Na from Na2CO3 + mols Na from NaHCO3.

    M Na = mols Na/total volume in L
