3.31 × 10^23 molecules

We are given;

The number of moles = 0.55 moles

We are required to calculate the number of molecules in 0.55 moles of sodium nitrate.

We know that 1 mole of a compound contains molecules equivalent to the Avogadro's number, 6.022 × 10^23.

Therefore;

1 mole of NaNO₃ = 6.022 × 10^23 molecules

Thus, for 0.55 moles will contain;

= 0.55 moles × 6.022 × 10^23 molecules

= 3.31 × 10^23 molecules

Hence, 0.55 moles will contain 3.31 × 10^23 molecules
