3.00 g of KCl is dissolved in 500.0 g of water to make an aqueous solution at 303 K. a. What is the concentration of KCl in ppm? b. What is the freezing point of this solution if 2.00 L of 0.100 M KCl (ρ = 1.05 g/mL) is added? The cryoscopic constant for water is 1.86 °C·kg/mol. Assume ideal behavior of the ions.

c. What is the vapor pressure in torr of the solution described in (b) at 303 K? You will need to look up the vapor pressure of water at this temperature.

a compound is a molecule made of atoms from different elements.

a. by the combination of an unlimited number of elements

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
