The vapor pressure of water can be estimated by the Antoine equation \(\log_{10} P = A - \frac{B}{C+T}\), where \(P\) is the pressure in mm Hg and \(T\) is the temperature in °C. For water in the range \(1^{\circ}\mathrm{C}\) to \(100^{\circ}\mathrm{C}\), the constants are \(A = 8.07131\), \(B = 1730.63\), and \(C = 233.426\). At a mountain station the atmospheric pressure is \(630\) mm Hg. Calculate the boiling point of water at this pressure (in °C).
