How do you calculate kg of solvent?
Calculate the number of kilograms of solvent.
- The mass of the solution is 1 L × (1000 mL / 1 L) × ( 1.02 g / mL) × (1 kg / 1000 g) = 1.02 kg.
- The mass of solute is 3.00 mol glucose × (180 g glucose / 1 mol glucose) × ( 1 kg / 1000 g ) = 0.54 kg.
- The mass of the solvent is 1.02 kg – 0.54 = 0.48 kg.
What is the molarity of a solution containing 7.0 moles of solute in a 569 mL of solution?
Therefore, the molarity of the solution is 12 M.
What is kilograms of solvent?
Molality is a measure of the number of moles of solute in a solution corresponding to 1 kg or 1000 g of solvent. This contrasts with the definition of molarity which is based on a specified volume of solution. A commonly used unit for molality in chemistry is mol/kg.
How do you find the molar mass of a solvent?
Step 1: List the known quantities and plan the problem. to calculate the molality of the solution. Then use the molality equation to calculate the moles of solute. Then divide the grams of solute by the moles to determine the molar mass.
What is the number of kilograms of solvent in a 0.70 molal solution containing 7.0 grams of solute?
Thus, the required weight of solvent in the solution is 0.238 kg.
What is the number of moles in 432 g Ba no?
The molecular weight is: Ba=137.33, N = 14.007 x 2, O = 16.00 x 6. Added together, it is 261.344. 432/261.344 = 1.653. Since the answer should have 3 significant figures, the answer should be 1.65 moles.
What is the molarity of a solution that contains 5.0 moles of solute in 5.0 l of solution?
The molarity of the solution is 5.1 mol/L .
What is the molarity of a solution that contains 0.525 moles of solute per 3.2 liters of solution?
What is the molarity of a solution that contains 0.50 mole of NaOH in 0.50 liter of solution? A 16.7⋅g mass of sodium sulfate is dissolved in a volume of 0.125⋅L of water. What is the concentration with respect to sodium sulfate? Calculate the molarity of the solute in a solution containing 14.2 KCl in 250 mL solution?
What is mass solvent?
mass(solvent) = moles(solute) ÷ molality. moles(NaCl) = 0.11 mol. molality = 1.3 m. mass(water) = 0.11 ÷ 1.3 = 0.085 kg = 85 g.
What is the mass in in of a solution?
The quantity of solute is expressed in mass or by moles. For a solution, the mass per cent is described as the grams of solute per grams of solution, multiplied by 100 to get the percentage.
