What is the molarity of a 2 L solution containing 0.5 moles NaCl? 0.25 M true 0.5 M false 1.0 M false 4.0 M false false 0 Single 0 A gaseous solution exerts 5 atm pressure. Following Dalton's Law of Partial Pressures, the solution's components: will also exert 5 atm of pressure false exert an average of 5 atm of pressure. false have a combined pressure of 5 atm true have equal pressures totalling to 5 atm false false 0 Single 0 According to this law, the pressure exerted by a nonvolatile solute is inversely related to its own concentration. Boyle's Law false Avogadro's Law false Henry's Law false Raoult's Law true false 0 Single 0 When you increase the molality of a solution: It takes a higher temperature to vaporize the solvent true It takes a higher pressure to vaporize the solvent false An amount of solvent will vaporize equal to the moles of solute false It will become a supersaturated solution false false 0 Single 0 Four solutions A, B, C, D have the same volume but different concentrations. Assuming all other conditions are equal, which solution will have the lowest temperature needed to reach freezing point? The solution with the highest concentration. true The solution with the lowest concentration. false All solutions will have the same freezing point. false None of the solutions will reach the freezing point. false false 0 Single 0 Which of the following situations demonstrates freezing point depression? Seawater has a lower freezing point than pure water. true Seawater freezes at -4°C while pure water freezes at 0°C. false Water ice has a lower density than liquid water. false Less amount of coffee can be dissolved in ice-cold water. false false 0 Single 0 Which of the following variables is essential in calculating the osmotic pressure of a solution? Partial pressure of the gaseous solute false Partial pressure of the gaseous solvent false molality of the solution false temperature true false 0 Single 0 NaCl is an example of an electrolyte because: saltwater conducts more electricity than pure water false NaCl dissociates into ions when in an aqueous solution true helps replenish water lost by sweat false it is formed from the electrolysis of two ions false false 0 Single 0 Who discovered how the dissociation of particles affects the colligative properties of a solution? Jacobus van't Hoff true François-Marie Raoult false John Dalton false Fritz London false false 0 Single 0 What happens when a cell is exposed to a hypertonic solution? It will retain its water content. false It will gain water from its surroundings. false It will lose water to its surroundings. true The cell becomes electrolyzed. false false 0 Single 0
