(a)

Interpretation Introduction

Interpretation: The number of moles of each of the given ions in sea water and the given moles of chloride are sufficient to form salts with magnesium and sodium ions or not is to be determined.

Concept introduction: The number of moles of the given element is calculated by dividing its mass with the molar mass.

To determine: The number of moles of ${\text{Cl}}^{-},{\text{Na}}^{+}$ and ${\text{Mg}}^{2+}$ ions in the given sample of seawater.

(b)

Interpretation Introduction

To determine: If the present amount of chloride ions are sufficient to make salt with ${\text{Na}}^{+}$ and ${\text{Mg}}^{2+}$.
