The vapor pressure (P) of solid ammonia is given by \( \ln(P) = 23.03 - \frac{3754}{T} \), while that of liquid ammonia is given by \( \ln(P) = 19.49 - \frac{3063}{T} \), where \( T \) is the temperature in K. The temperature of the triple point of ammonia is ________ K (rounded off to two decimal places).
