Consider that you prepared a solution by mixing 0.15 g solute with 7.59 g of solvent. If you measured that the solution had a molality of 0.164 m, what is the molar mass of the solute? Express your answer numerically to three significant figures.
Consider that you prepared a solution by mixing 0.21 g solute with 9.52 g of solvent. If you measured that the solution had a molality of 0.154 m, what is the molar mass of the solute? Express your answer numerically to three significant figures.
Consider that you prepared a solution by mixing 0.19 g solute with 8.72 g of solvent. If you measured that the solution had a molality of 0.178 m, what is the molar mass of the solute? Express your answer numerically to three significant figures.
A solution contains 0.180 g of an unknown nonelectrolyte solute in 50.0 g of water. The solution freezes at –0.040 0C (notice the negative sign). A) What is the molar mass of the unknown solute? B) What is the boiling temperature of the solution? Kf(water) = 1.86 K kg mol-1 ; Kb(water) = 0.51 K kg mol-1 . Assume that the solute only exists as a monomer in aqueous solution.
For a solution composition of 25.0 g solute and 100.0 g solvent; choose the correct numerical concentration of % (m/m). 20.0 15.0 10.0 25.0 Question 25 2 pts Characterize EACH of the three given statements as being TRUE or FALSE and then indicate the collective true false status of the statements using the choices. (1) 1.0 liters of a 6.0 M solution would contain 6.0 moles of solute, independent of the identity of the solute. (2) For liquid-liquid solutions, volume...
Concentrations of solute in solvent, whether in saturated solutions or not, can be expressed in many ways (molarity, molality, ppm, percent by mass, etc.). Molarity = moles of solute / liter of solution molality = moles of solute / kg of solvent ppm = mg solute / liter of solution ppb = microgram of solute / liter of solution %-by-mass = (grams of solute / grams of solution) x 100% To convert from %-by-mass to Molarity, assume 100g of solution,...
A cell that contains 22% solute is in a beaker that contains 22% solvent. Which of the following is correct? o The cell is hypotonic to the solution in the beaker o The cell is hypertonic to the cell in the beaker o The cell is isotonic to the solution in the beaker The correct one is the first one according to my professor. I am confused on why it is. Do we ignore the water in the cell and...
