What is the boiling point of a solution of 0.10 mole of glucose in 200ml of water?
To determine the boiling point of a solution of glucose in water, we first calculate the molality of the solution. With 0.10 moles of glucose in 200 mL of water (approximately 0.2 kg), the molality is 0.5 mol/kg. The boiling point elevation can be calculated using the formula ΔT_b = i * K_b * m, where K_b for water is 0.512 °C kg/mol. Thus, the boiling point elevation is approximately 0.26 °C, raising the boiling point of water from 100 °C to about 100.26 °C.

What is the boiling point of glucose dissolved in water?
The boiling point of a solution can vary depending on the concentration of solute. For a dilute solution of glucose in water, the boiling point elevation is typically small and may not be easily measurable. However, pure glucose itself does not have a defined boiling point as it decomposes upon heating.
Why does the KCI solution have the higher boiling point if in a experiment 1 mol KCLid dissolved in a 1.4 kg sample of waater the 1mol glucose ids dissolved i another 1.4kg sample of water?
The KCl solution has a higher boiling point than the glucose solution due to the presence of ions. KCl dissociates into potassium (K⁺) and chloride (Cl⁻) ions in solution, effectively increasing the number of solute particles (colligative properties). In contrast, glucose does not dissociate and remains as intact molecules, resulting in fewer solute particles. This increase in particle concentration in the KCl solution elevates its boiling point through boiling point elevation.
What is boiling point of 1 molar glucose solution?
A 1 molar solution by definition is 1 mole of something, in this case glucose, in 1 liter of solution. The molecular weight of something can be found on the perdiodic table. The weight listed on the periodic table is the grams in a mole, these of course are for atoms. 12 H + 6 C +6O + 188.1558 grams in a mole of glucose. Put this weight into one liter of water.
What happpens to the boiling point of a solution?
At the boiling point liquids become gases and if the solution contain dissolved solids they remain as residues.
Calculate the boiling point elevation of an aqueous solution of 0.14 m glucose?
The boiling point elevation of a solution can be calculated using the equation ΔTb = i * Kb * m, where i is the van't Hoff factor (1 for glucose), Kb is the ebullioscopic constant for water (0.512 °C/m), and m is the molality of the solution (0.14 m). Plugging in these values, we get ΔTb = 1 * 0.512 * 0.14 = 0.07168 °C. So, the boiling point elevation of the solution is 0.07168 °C.

What is the boiling point of water glucose?
The boiling point of water is 100 degrees Celsius. Glucose, on the other hand, does not have a fixed boiling point because it decomposes before reaching a boiling point.
The boiling point of a liquid solution is?
Higher then the boiling point of the solvent.

The difference between the boiling point of a liquid in pure state and the boiling point of the liquid in solution?
Boiling Point Elevation
What is the boiling point of concentrated aqueous solution of sodium chloride?
The boiling point of a concentrated aqueous solution of sodium chloride is higher than that of pure water. This is due to the presence of the solute, which raises the boiling point of the solution through a process called boiling point elevation. The exact boiling point will depend on the concentration of the sodium chloride in the solution.
What is the freezing and boiling point to glucose?
Melting (freezing) point: α-D-glucose: 146 °C β-D-glucose: 150 °C Glucose will decompose already below its boiling point, so there's no valued boiling point (at least not at normal pressure).
How can one determine the boiling point of a solution?
The boiling point of a solution can be determined by measuring the temperature at which the solution changes from a liquid to a gas. This temperature is typically higher than the boiling point of the pure solvent due to the presence of solute particles in the solution.
What happpens to the boiling point of a solution?
At the boiling point liquids become gases and if the solution contain dissolved solids they remain as residues.
Calculate the boiling point elevation of an aqueous solution of 0.14 m glucose?
The boiling point elevation of a solution can be calculated using the equation ΔTb = i * Kb * m, where i is the van't Hoff factor (1 for glucose), Kb is the ebullioscopic constant for water (0.512 °C/m), and m is the molality of the solution (0.14 m). Plugging in these values, we get ΔTb = 1 * 0.512 * 0.14 = 0.07168 °C. So, the boiling point elevation of the solution is 0.07168 °C.
