Ethanol (C2H6O; P° = 59.02 torr at 25 °C) and acetone (C3H6O; P° = 225.02 torr at 25 °C) are liquids that mix uniformly at all proportions at 25 °C. An undergradute student prepared a mixture of the 2 liquids and found to have a vapor pressure of 90.51 torr at 25 °C. He was able to record the mass of the acetone was used, which was 63.50 g, but forgot to jot down the mass of the ethanol in his data notebook. Based on the data collected, how much ethanol (in g) was used to prepare the said mixture?
