Sagot :
The theoretical yield of the reaction is 1.13 g. The acid H₃PO₄ is the limiting reactant.
Definition of the theoretical yield
The theoretical yield of a given chemical reaction can be obtained from the balanced reaction equation.
Number of moles of Cr = 0.50 g /52 g/mol = 9.6 × 10⁻³ moles
Number of moles of acid = 0.75 g/98 g/mol = 7.7 × 10⁻³ moles
Given that the reaction is 1:1, the limiting reactant would be the acid.
The theoretical yield that is obtained from,
Theoretical yield = Number of moles of product × Molar mass of product
Substitute the values to obtain,
7.7 × 10⁻³ moles × 147 g/mole = 1.13 g
