Late on an autumn day, the relative humidity is 47.5% and the temperature is 20.0\"C. What will the relative humidity be that evening when the temperature has dropped to 10.0C, assuming constant water vapor density? Take the saturation vapor density at 20.0\"(3 to be 17.2 g/m3 and at 10.0C to be 9.40 g/m3. "/0
