3. The mutual solubilities of two liquids A and B at one atmosphere and various temperatures, are given in the table below: Temperature Weight % of A 293 K 12.3 89.6 313 K 15.1 86.4 333 K?

To find the weight % of A at 333 K, we can use the concept of mutual solubilities. At 333 K, the weight % of A is not directly given in the table, but we can interpolate between the values given at 313 K and 293 K.

First, calculate the difference in weight % of A between 313 K and 293 K:
15.1% - 12.3% = 2.8%

Next, calculate the difference in weight % of A between 333 K and 313 K:
86.4% - 15.1% = 71.3%

Now, calculate the weight % of A at 333 K using the interpolation formula:
Weight % of A at 333 K = Weight % of A at 313 K - (Difference at 313 K * (Difference at 333 K / Difference at 313 K))
Weight % of A at 333 K = 15.1% - (2.8% * (71.3% / 2.8%))
Weight % of A at 333 K = 15.1% - (2.8% * 25.46)
Weight % of A at 333 K = 15.1% - 71.288%
Weight % of A at 333 K = 15.1% - 71.3%
Weight % of A at 333 K = -56.2%

Therefore, the weight % of A at 333 K is -56.2%. This result is not physically meaningful, so there may be an error in the calculations or the data provided.

The provided context does not include the data for 333 K. Therefore, I cannot extract the requested information from the given context.
