Answer :
Final answer:
Without specific data or a formula to determine the vapor pressure of the unknown substance at 29°C, it is not possible to accurately choose an answer from the given options with the provided information.
Explanation:
The subject question requires the determination of the vapor pressure of a substance at 29°C. Unfortunately, the tables provided do not give specific vapor pressures at 29°C, or for a substance with a boiling point near this temperature. The given tables include general vapor pressure data for selected compounds, the vapor pressure of water at selected temperatures, and similar examples using vapor pressures to illustrate various principles in chemistry.
Without additional information about the specific substance in question, or a more detailed table of its vapor pressures at various temperatures, or a formula such as the Clausius-Clapeyron equation to extrapolate or interpolate the values, we cannot accurately determine the vapor pressure of the substance at 29°C. Therefore, with the available data, it's not possible to determine the correct answer from the options provided.
