1. The atmosphere of Venus is 90 times more massive (based on the surface pressure) than Earth, yet Mercury has almost no atmosphere. Explain why the atmospheres of these two planets are so different. Use at least three factors we discussed in class to explain the differences (gravity, surface temperature, composition). Don't be vague - be specific - which will require you to do some research into the characteristics of each planets' atmosphere. (6)

The vapor pressure of chloroform is 173.11 mm Hg at 25°C. How many grams of testosterone, C19H28O2, a nonvolatile, nonelectrolyte (MW = 288.4 g/mol), must be added to 292.3grams of chloroform to reduce the vapor pressure to 169.77 mm Hg ? chloroform = CHCl3 = 119.40 g/mol. Answer in - g testosterone Round to appropriate significant figures

II Revi Part A The vapor pressure of a substance describes how readily molecules at the surface of the substance enter the gaseous phase. At the boiling point of a liquid, the liquid's vapor pressure is equal to or greater than the atmospheric pressure exerted on the surface of the liquid. Since the atmospheric pressure at higher elevations is lower than at sea level, the boiling point of water decreases as the elevation increases. The atmospheric pressure at sea level...
