A:If 100 mL of a 0.15 M Mg(NO3)2(aq) solution has a density of 1.09 g/mL, which of the following statements is false? Group of answer choices The mass of Mg(NO3)2 in this solution can be determined from this information. If the solution density was not given, it is usually reasonable to assume 1.00 g/mL The mass of the water in this solution is 109 g It is possible to determine the mole fraction of water in this solution. B: In the body, cell membranes act like semipermeable membranes discussed in class. If a red blood cell is surrounded by fluid with a higher electrolyte concentration than what is inside the cell, which of the following statements is true? Group of answer choices The cell will shrink because water will pass from the inside of the cell to the fluid The surrounding fluid has a lower osmotic pressure than what is inside the cell The cell will swell up because water will pass from the fluid to the inside of the cell Nothing will happen to the cell
