You can consult a table of water vapor partial pressures over hydrochloric acid solutions, and then calculate the value. The unit for P is mmHg, while the unit for T is K. The calculation formula is as follows: lgP = A – B/T. For a hydrochloric acid concentration of 40%, the values from the table are A = 9.33923 and B = 2647. For a concentration of 42%, the corresponding values are A = 9.44953 and B = 2709. You’ll need to carry out the calculation yourself.
