The mass of sodium phosphate required to precipitate 4 .8 g calcium chloride is to be calculated. Concept introduction: The molar mass is used as the conversion factor to calculate the required mass of reactant needed to precipitate the other reactant. The stoichiometry of both the reactants is required from the balanced chemical reaction to calculate the mass of the reactant. Mass to mole conversion factor = number of moles of compound molar mass of compound Mole to mole conversion factor= number of moles of product number of moles of reactant Mole to mass conversion factor = molar mass of compound number of moles of compound For theoretical yield, steps are mass to mole conversion → mole to mole conversion → mole to mass conversion.

Interpretation Introduction
Interpretation:
The mass of sodium phosphate required to precipitate 4.8 g calcium chloride is to be calculated.
Concept introduction:
The molar mass is used as the conversion factor to calculate the required mass of reactant needed to precipitate the other reactant.
The stoichiometry of both the reactants is required from the balanced chemical reaction to calculate the mass of the reactant.
Mass to mole conversion factor = number of moles of compoundmolar mass of compound
Mole to mole conversion factor=number of moles of productnumber of moles of reactant
Mole to mass conversion factor = molar mass of compoundnumber of moles of compound
For theoretical yield, steps are mass to mole conversion → mole to mole conversion → mole to mass conversion.
These are in the wrong boxes. Why does the one on the left have a lower molar mass than the one on the right?
