Answer to Question #141775 in General Chemistry for gia

Question

 A bleaching solution contains sodium hypochlorite, NaClO, dissolved in water. The solution is 0.650 m NaClO. What is the mole fraction of sodium hypochlorite?

Answer 1

n(H2O)=m/M=1000/18=55.556(mol)

n(NaClO)=0.650(mol)

n_total=55.556+0.650=56.206(mol)

X=n(NaClO)/n_total=0.650/56.206=0.012
