The boiling point elevation of an aqueous sucrose solution is found to be 0.67°C. What mass of sucrose (molar mass= 342.30 g/mol) would be needed to dissolve in 500.0 g of water? Kb (water) = 0.512°C/m.

Methane (CH4) has a Henry’s Law constant (k) of 9.88 x 10–2 mol/(L·atm) when dissolved in benzene at 25°C. How many grams of CH4 will dissolve in 3.00 L of benzene if the partial pressure of CH4 is 1.48 atm? The molar mass of methane is 16 g/mole.  

Use the diagram below to answer the following questions.What phases can be present at 200°C and 0.75 atm pressure?

Calculate the number of moles of sulfuric acid that is contained in 250 mL of 0.500 M sulfuric acid solution.

For the following problem, use a separate sheet of paper to solve the problem and then upload your solution at the following link: https://canvas.dccc.edu/courses/28279/assignments/560402 Your work must be shown for full credit.  The answer alone is only worth 1 point.    Hexachlorophene is used as a disinfectant in germicidal soaps. What mass of hexachlorophene ( Molar mass = 406.9 g/mol) must be added to 125 g of chloroform to give a solution with a boiling point of 62.60°C? Kb = 3.63°C/m, boiling point of pure chloroform = 61.70°C

The critical temperature of a substance is the

The _________ is the smallest unit of organization that can perform all activities required for life.

True or False: A eukaryotic cell is enclosed by a plasma membrane while a prokaryotic cell is not.  Both eukaryotic and prokaryotic cells contain their genetic information in DNA.

True or False: A hypothesis is an explanation, based on observations and assumptions, that leads to a testable prediction.  A hypothesis on supernatural events can also be explained through experimental tests.
