Answer:

The mole fraction of NaCl is 0.1885

Explanation:

We are given;

  • Moles of NaCl = 2.3 moles
  • Moles of KCl = 5.3 moles
  • Moles of NaOH = 4.6 moles

We are required to calculate the mole fraction of NaCl

Mole fraction will be given by getting a ratio of moles of NaCl to the total number of moles.

In this case;

The total number of moles = 2.3 moles + 5.3 moles + 4.6 moles

                                            = 12.2 moles

Therefore;

Mole fraction of NaCl = 2.3 moles ÷ 12.2 moles

                                    = 0.1885

Hence, the mole fraction of NaCl is 0.1885
