Final answer:
The experimentally determined molar ratio of Na₂CO₃ to NaCl. 1 mol Na₂CO₃: 0.038 mol NaCl is a) Correct.
Step-by-step explanation:
A mole ratio is a conversion factor that relates the amounts in moles of any two substances in a chemical reaction.
It is represented by the ratio of the coefficients of the balanced chemical equation
The question asks to calculate the experimentally determined molar ratio of Na₂CO₃ to NaCl.
Given that the molar ratio is 1 mol Na₂CO₃ to 0.038 mol NaCl.
To calculate this ratio, we divide the number of moles of Na₂CO₃ by the number of moles of NaCl.
In this case, the molar ratio would be:
1 mol Na₂CO₃ / 0.038 mol NaCl = 26.32 mol Na₂CO₃ / mol NaCl
This means that for every 1 mole of NaCl, there are approximately 26.316 moles of Na₂CO₃.
Therefore, the correct answer is a) Correct.
