Answer;

= 9.45 × 10^23 molecules

Explanation;

The molar mass of Na2SO4 = 142.04 g/mol

Number of moles = mass/molar mass

                             = 223/142.04

                             =  1.57 moles

But;

1 mole = 6.02 × 10^23 molecules

Therefore;

1.57 moles = ?

= 1.57 × 6.02 × 10^23 molecules

= 9.45 × 10^23 molecules
