question

Khudseneffusion technique was used to determine the vapor pressure of scandium and the following data were obtained temperature, 1555.4°K time, 110.5 min weight loss and diameter of orifice were 9.57 mg and 0.2965 cm, respectively. Use the above data to estimate the vapor pressure of scandium at 1555.4°K and 1 atm.
