The Ratio of Methanol to Water Vapor Pressure at 45C,Calculate the ratio of methanol (vapor pressure = 410 torr at 45C) to water (vapor pressure = 70 torr at 45C)

The Ratio of Methanol to Water Vapor Pressure at 45C

At 45 degrees Celsius, the vapor pressure of methanol and water can be compared to determine their ratio. Methanol has a vapor pressure of 410 torr and water has a vapor pressure of 70 torr at 45C (Seymour, 2019). As a result, the ratio of methanol to water vapor pressures is 5.86:1. In order to calculate the ratio, the vapor pressure of methanol must be divided by the vapor pressure of water. The vapor pressure of methanol is 410 torr and the vapor pressure of water is 70 torr (Seymour, 2019). When divided, 410/70 = 5.86. This equation produces a ratio of methanol to water vapor pressure at 45C of 5.86:1. While the vapor pressure of methanol is significantly greater than the vapor pressure of water at 45C, it is important to note that the vapor pressure of water is higher than the vapor pressure of methanol at temperatures below 45C. This is due to the fact that methanol has a higher boiling point than water (Seymour, 2019). Cont…
