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.

Which statements are true concerning mineral formation? check all that apply. the slower the cooling, the larger the crystals. the faster the cooling, the smaller the crystals. crystals formed from magma are smaller than crystals formed from lava. minerals can only form in solutions when the solution is heated deep underground. when a solution cools, elements and compounds leave the solution and crystallize as minerals. minerals formed from hot water solutions can form narrow channels in the surrounding rock.
