Heterogeneous and homogeneous
When determining the concentration of an acid solution, the titrant would usually be put in the burette while the analyte would be in the conical flask.
The titrant is usually a known solution while the analyte would be the unknown solution.
In order to determine the concentration of a solution of hydrofluoric acid, the acid would need to be titrated against a suitable base of known concentration using a suitable indicator to indicate the endpoint of the neutralization reaction.
Thereafter, the volume of the titrant used would be recorded and used to find the concentration of the acid (the analyte).
Thus, since the base would be known, it would be the one in the burette while the hydrofluoric acid would be the one in the conical flask.

Answer:
40.68kPa
Explanation:
The remaining part of the question is requesting to calculate the pressure (p2) after increase in volume.
Data;
V1 = 21.3mL
P1 = 98.8 kPa
V2 = 52.7 mL
P2 = ?
Using Boyle's law,
PV = K
P1V1 = P2V2
98.8 * 21.7 = p2 * 52.7
P2 = 2143.96 / 52.7
P2 = 40.68 kPa
Note I didn't convert the values since they all have the same unit.
