That would be cause part of the sodium is pure and that means it still kind of has it properties when it was an element and that its i think.
L

mol/dm³ is measure for molarity
Answer:
1.80 × 10²⁴ Molecules of Sucrose
Solution:
Number of Moles and Number of Particles (molecules in given case) are related to each other as,
Moles = Number of Molecules ÷ 6.022 × 10²³
Solving for Number of Molecules,
Number of Molecules = Moles × 6.022 × 10²³
Data Given;
Moles = 3 moles
Putting values in eq,
Number of Molecules = 3 mol × 6.022 × 10²³
Number of Molecules = 1.80 × 10²⁴ Molecules
