Question
A nonvolatile organic compound Z was used to make up a solution. Solution A contains 8.00 g of Z dissolved in 100 g of water
A nonvolatile organic compound Z was used to make up a solution. Solution A contains
8.00 g of Z dissolved in 100 g of water and has a vapor pressure of 754.5 mmHg at the normal boiling point of water. Calculate the molar mass of Z in solution A.
At 2C, the vapor pressure of pure water is 23.76 mmHg and that of a certain seawater sample is 23.01 mmHg. Assuming that seawater contains only NaCl, estimate its molal concentration.
