An aqueous solution of 10.00 g of an enzyme has a volume of 1.00 L at 29°C. The solution's osmoticpressure at 29°C is found to be 0.781 torr. Calculate the molar mass of the enzyme.
How does exchange of nutrients, wastes and gasses occur at the capillary level? What two pressures are involved and how do they create a difference in net pressure from the arterial end to the venous end of the capillary? Please be specific.
There was an experiment conducted to determine the osmotic potential of potato tissue.
The osmotic potential of various concentrations of sucrose solutions are provided in the table below.
Sucrose Concentration Osmotic Potential

What are roles of osmotic potential or turgor pressure in regulating water potential of plant cells? Exp
How is reverse osmosis related to the colligative properties of solutions?
What are other colligative properties? How are they similar or different? What common factors are present in equations for colligative properties?
Why do you think any given factors are associated with a particular colligative property?
The alcohol content of hard liquor is normally given in terms of the "proof", which is defined as twice the percentage by volume of ethanol (C2H5OH) present. Calculate the number of grams of alcohol present in 1.00 L of 51 proof gin. The density of ethanol is 0.798 g/mol. (solution in grams, please)

Red blood cells are placed into pure water. Which of the following statements is true?
A) water molecules flow out of the red blood cells, causing them to collapse
B) water flows into the red blood cells, causing them to swell and burst
C) the osmoticpressure of the cell contents increases, causing the cells to b
1.) In the reaction CaO(s) + SO2(g) YEILDS CaSO3(s),
Which is correct:
O2- acts as a Lewis base, and SO2 acts as a Lewis acid.
Ca2+ acts as a Lewis base, and SO42- acts as a Lewis acid.
SO42- acts as a Lewis base, and SO2 acts as a Lewis acid.
SO2 acts as a Lewis base, and O2- acts as a Lewis acid.
SO2 act
