Answer:
The ratio of moles of Na to NaCl can be found using the balanced chemical equation for the formation of NaCl from its constituent elements:
2 Na + Cl2 → 2 NaCl
From the equation, we can see that two moles of Na react with one mole of Cl2 to produce two moles of NaCl. Therefore, the ratio of moles of Na to NaCl is 2:2, or simply 1:1.
Alternatively, we can use the relative atomic masses of Na and Cl to calculate the ratio of moles:
The molar mass of Na is 23 g/mol (from the periodic table).
The molar mass of NaCl is 23 + 35.5 = 58.5 g/mol.
The ratio of moles of Na to NaCl is therefore:
(1 mole Na) / (23 g/mol Na) : (1 mole NaCl) / (58.5 g/mol NaCl)
= 1 : 2.54
Therefore, the ratio of moles of Na to NaCl is approximately 1:2.54
