15.0g of calcium carbonate is present in 250g of water. if the water has a temperature of 30c, what is the resulting vapor pressure of the water in solution? ( the vapor pressure of pure water at 300C is 53.196 kPa)

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

the answer is 303.15 or 303

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
