Answer: 51.4 g of NaClO will be produced.

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}    

\text{Moles of} Cl_2=\frac{48.9g}{71g/mol}=0.69moles

\text{Moles of} NaOH=\frac{54.2g}{40g/mol}=1.4moles

2NaOH+Cl_2\rightarrow NaCl+NaClO+H_2O

According to stoichiometry :

1 moles of Cl_2 require = 2 moles of NaOH

Thus 0.69 moles of Cl_2 will require=\frac{2}{1}\times 0.69=1.38moles  of NaOH

Thus Cl_2 is the limiting reagent as it limits the formation of product and NaOH is the excess reagent.

As 1 mole of Cl_2 give = 1 mole of NaClO

Thus 0.69 moles of Cl_2 give =\frac{1}{1}\times 0.69=0.69moles  of NaClO

Mass of NaClO=moles\times {\text {Molar mass}}=0.69moles\times 74.5g/mol=51.4g

Thus 51.4 g of NaClO will be produced
