5. Assuming that NaCl dissociates completely into its ions when dissolved in water, how much sodium chloride must be dissolved in 5.50 kg of water to lower the
freezing point from 0°C to -10.0°C?

> 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.

what is the question here. i think you messed up.

diaria maybe go see a doctor about that
