Determine the theorical yield (in grams) of strontium
sulfate. What is your limiting reactant and excess reactant?
given 2.27×10^-3 mol Na2SO4 and 2.5×10^-3 mol SrCl2
The reaction of Na2SO4 and SrCl2 are following:
Na2SO4 + SrCl2 -- > SrSO4 + 2NaCl
Given that moles of SrCl2: 2.5×10^-3 mol SrCl2
Na2SO4: 2.27×10^-3 mol Na2SO4
SrCl2 due to following reasons:
2.5×10^-3 mol SrCl2 * 1 mole SrSO4/ 1 Mole SrCl2
2.5×10^-3 mol SrSO4
the theatrical yield (in grams) of strontium sulfate= Number of moles* molar mass
= 2.5×10^-3 mol SrSO4*183.68 g/mol
= 0.4592 g SrSO4
