What is the molality of a solution composed of 20.2 g NaCl dissolved in 685 g of water?
The answer is 0,505.
What is the molality of a solution that contains 2 moles of glycerin and dissolved in 1000 g of water?
The molality of a solution is calculated by dividing the moles of solute by the mass of the solvent in kilograms. In this case, there are 2 moles of glycerin dissolved in 1000 g of water, which is equivalent to 1 kg. Therefore, the molality is 2 mol / 1 kg = 2 mol/kg.
Formula for molality?
Molality (m) is calculated by dividing the number of moles of solute by the mass of the solvent in kilograms and is expressed in mol/kg. The formula for molality is: [ molality (m) = \frac{moles\ of\ solute}{mass\ of\ solvent\ in\ kg} ]
What would you need to do to calculate molality of 10g of NaCI in 2Kg of water?
To calculate the molality of a solution, you need to divide the moles of the solute (in this case, NaCl) by the mass of the solvent (water) in kilograms. First, convert the mass of NaCl to moles using its molar mass. Then, calculate the molality by dividing the moles of NaCl by the mass of water in kilograms.
How can you express the concentration of a substance mathematically?
In chemistry, the concentration of a substance in solution is determined by molarity, which is symbolized by "M". This indicates the number of moles of a substance dissolved in one liter of a solvent (usually water). For example: - 1 mole of sodium chloride = 58 grams - If 116 grams of sodium chloride are dissolved in 1 liter of water, then that solution is a 2-molar (2 M) solution of sodium chloride. - If 232 grams of sodium chloride are dissolved in 1 liter of water, then that solution is a 4-molar (4 M) solution of sodium chloride.
What is the molality of a solution of 75.2 g AgClO4 dissolved in 885 g C6H6?
To calculate molality, we first need to find the moles of AgClO4 and the moles of solvent, C6H6. Calculate moles of AgClO4: 75.2 g / molar mass of AgClO4 Calculate moles of C6H6: 885 g / molar mass of C6H6 Then, molality (m) = moles of solute / kg of solvent. Divide the moles of AgClO4 by the kg of C6H6 to find the molality of the solution.
What is the molality of a solution containing 10.0g of Na2SO4 dissolved in 1000.0g of water?
To find the molality, we first calculate the moles of Na2SO4: 10.0g Na2SO4 * (1 mol Na2SO4 / 142.04g Na2SO4) = 0.0705 moles Na2SO4. Then, molality is calculated as moles of solute (Na2SO4) / kilograms of solvent (water): 0.0705 mol / 1.000 kg = 0.0705 mol/kg, which is the molality of the solution.
What is the molality of a solution in which 0.3 moles of solute is dissolved in 1000ml of solvent?
The molality of a solution is calculated by dividing the moles of solute by the mass of the solvent in kilograms. First, convert the volume of the solvent from milliliters to liters (1000 ml = 1 L). Then calculate the molality using the formula: molality = moles of solute / (mass of solvent in kg).
What is the molality of solution that has 3 mol of glucose in 6 Kg of water?
3mol/6kg
Is calcium chloride dissolved in water an electrolyte or nonelectrolyte solution?
Calcium chloride dissolved in water is an electrolyte solution. When calcium chloride is dissolved, it dissociates into calcium ions (Ca²⁺) and chloride ions (Cl⁻), which are capable of conducting electricity in the solution.
What is the amount of dissolved substance in a solution called?
The amount of dissolved substance in a solution is called the concentration of the solution. This can be expressed in various units such as molarity, molality, or weight/volume percentage.
What is the molality of a solution composed of 20.2 g NaCl dissolved in 685 g of water?
The answer is 0,505.
When sodium chloride is dissolved in water the resulting solution is classified as a?
When sodium chloride is dissolved in water, the resulting solution is classified as an electrolyte solution. This means that it conducts electricity due to the presence of ions in the solution. Sodium chloride dissociates into sodium ions and chloride ions when dissolved in water.
What is the molality of a solution that has 6 mol of cacl2 in 3kg of water?
The molality of a solution is calculated by dividing the moles of solute by the mass of the solvent in kilograms. In this case, the molality of the CaCl2 solution would be 2 mol/kg, as 6 mol of CaCl2 dissolved in 3 kg of water results in a molality of 2 mol/kg.
When sodium chloride is dissolved in water the solution is homogeneous?
The sodium chloride solution of sodium chloride in water is homogeneous.
What is sodium chloride solution?
This solution contain a specified concentration of sodium chloride.
What is the molality of a solution made by dissolving 2 moles of NaOH in 10 kg?
The molality of a solution is calculated by dividing the moles of solute by the mass of the solvent in kilograms. In this case, with 2 moles of NaOH dissolved in 10 kg of water, the molality would be 0.2 mol/kg.
