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)

Astudent pours 10.0 g of salt into a container of water and observes the amount of time it takes for the salt to dissolve. she then repeats the process using the same amounts of salt and water but this time she slowly stirs the mixture while it is dissolving. the student performs the experiment one more time but this time she stirs the mixture rapidly. the dependent variable in this experiment is: time for salt to dissolve speed of stirring amount of water mass of salt
