Final answer:
To find the mass of potassium phosphate formed, one must first balance the given reaction, calculate the moles of reactants, identify the limiting reactant, and use stoichiometry to find the mass of the product.
Step-by-step explanation:
The subject of this question is stoichiometry, which is a part of Chemistry, involving the calculation of the amounts of reactants and products in chemical reactions. The problem provided is a typical high school level stoichiometry question where one needs to calculate the mass of potassium phosphate formed from a given mass of potassium hydroxide and cobalt (II) phosphate.
Firstly, balance the chemical equation given: 3KOH (aq) + Co3(PO4)2 (aq) → 3K3PO4 (aq) + Co(OH)2 (s).
To solve this, calculate the moles of each reactant using their molar masses, determine the limiting reactant, and then use it to find the mass of the product formed (potassium phosphate in this case), based on stoichiometric coefficients from the balanced equation.
