A gas has a solubility in water of 11.9 g/L at 15°C and 505 kPa of pressure. What is the pressure of the gas, in atm., (at the same temperature) if the solubility of the gas is 20 mg/L? 734 grams of lithium sulfate are dissolved to make 2500.0 mL of solution. What is the Molarity of this Solution

Describe the process you would follow to prepare 120 ml of a 2.0 M solution of HCl if you started with a 6.0 M stock solution.

What is the percent (mass/volume) if 12 g of KCl is added to 50 mL of water to make 93 mL of solution?

If 75 g. of Potassium Chloride (ionic compound) is dissolved in 250 grams of water, what will be the freezing point of the solution? Kf = 1.86

The vapor pressure of pure water is 3.17 kPa. What will be the vapor pressure of a solution containing 13 g. of potassium permanganate (KMnO4) and 750 g of water?

Ais a mountain created from eruptions of lava, ash, rocks, and hot gases.

The last few miles of the marathon are the most difficult for heather, her hair plastered to her head, sweat clinging to her arms, and her legs already feeling as if they had nothing left, just dead weight. after grabbing a cup of ice water, she feels the ice cubes smash against her nose as she gulps some cool refreshment and keeps on running. in these last few miles, the breeze kicks up and she finally feels some coolness against her skin. drips of sweat, once clinging to her forehead, now spill down, and heather feels more pain as the sweat flows into her eyes.which of the following is the most likely reason why the ice struck heather’s nose when she took a drink? a) water can function as a solvent. b) water can store large amounts of heat. c) water can moderate temperatures through evaporative cooling. d) the density of water decreases when it freezes. e) water has a cohesive nature.sweat remained on heather’s forehead and arms because of the a) high salt content of sweat b) cohesive nature of water c) ability of water to moderate heat d) high evaporative cooling effect of water e) ability of water to act as a solvent
