If the human kidneys secret 0.300 moles of urea per kilogram of water from blood plasma to urine, calculate Delta G at 37.5 degree C, given the concentrations of urea and blood plasma are 0.325 mole per kilogram and 0.006 mole per kilogram. Calculate the value of Delta_r G degree for the following alcohol fermentation: alpha-D-glucose_(aq) rightarrow 2 C_2H_5OH_(l) + 2 CO_2(g)
74 Percent Concentration -The amount of solute dissolved in a fixed amount of solvent is called the concentration of the solution. Concentrations are typically expressed as Mass al.) (% m/m) which is the mass of the solute (g) divided by the mass of the solution [solute+ solvent] (g)x 1000/0; or as Volume ol.) (% v/v ) which is the volume of the solute in a fixed volume of solution (1O0mL of solution) x 1000/0; or less commonly in the laboratory,...
Freezing points are lowered as a function of the number of moles of solute particles per kilogram of solvent. This is expressed mathematically with the following equation ATt Xkxi (mgolvending) where AT, is the amount by which the freezing point is lowered, Toute is the number of moles of solute, m ening is the mass of the solvent (in kilograms). ke is the freezing point depression constant which is specific to the solvent, and, i is the number of particles...
18. Acidity of a solution is determined by the concentration Hof hydrogen ions in the solution (measured in moles per liter of solution). Chemists use the negative of the logarithm of the concentration of hydrogen ions to define the pH scale. pH = -log H Solution A has a pH value of 5.6 and solution B has a pH value of 2.7. Compare the acidity of the two solutions. a) Solution A is more acidic by a factor of 2.07...
What is the relationship between the moles of solute and the mass of solute? Rewrite the molality expression in terms of grams and molecular weight. Background: Properties that depend on the concentration of particles in solution are called colligative properties. The number of particles in a solvent can affect the freezing or boiling point of solvent. To express the effect of concentration on freezing point or boiling point, molality is used in place of molarity. Molality (m) is the number...
11.) A 225ml solution is discovered to have a concentration of 1.95 moles per liter. What is the final volume to which the solution must be diluted for the concentration to become 1.00 moles per liter?
If 6M concentration means that there are 6 moles of HCl per liter of the solution and we know volume needed is 0.5 ml what is the moles, molecular weight, and mass (g) of HCl?
Question 3 Molality is defined as: e m= moles solute / kg solvent 6. M=moles of solute/ Lt of solution c. A and B are corrects d. m= moles of solute/ml of solvent
