Use this key to answer all the problems below. If you choose B or C, rewrite the statement so that it is complete and true. A = TRUE B = FALSE C = NOT ENOUGH INFORMATION. PROBLEM ONE: The initial molar concentration of the cytoplasm inside a cell is 2M and the cell is placed in a solution with a concentration of 2.5M.
Molarity - Quia
Molarity is a means of representing a solution’s concentration. In other words, it expresses how much dissolved solute can be expected from a given volume of solution. The . molar concentration or molarity, M, of a solution is used to indicate the number of moles of solute per liter of solution:

(Hint: Use the density and molar mass of water.) What happens to the concentration of water when a solute is dissolved in it? (1000 g/L) / 18.0 g/mol = 55.6 mol/L. The concentration of water decreases as a the concentration of a solute increases because the solute occupies some of the volume and the water molecules are pushed apart. 4
