Hence, the mole fraction of HCl is 0.1 and mole fraction of water is 0.9 in a 20% w/w aqueous HCl solution.
How do you find the mole fraction of HCl?
To calculate the mole fraction of HCl, we first convert mass to moles and then use Equation 13.4: (b) To calculate the molality of HCl in the solution, we use Equation 13.6, where water is the solvent. We calculated the number of moles of HCl in part (a), and the mass of solvent is 64 g = 0.064 kg.
What is the mole fraction of HCl in a 11.4% by mass aqueous solution?
The mole fraction of HCl in the solution is c. 0.0520.
What is the mole fraction of HCl in a solution that is prepared by dissolving?
Answer Expert Verified
M(HCl) = 5.5g/ mole of HCl , so mole of HCl = 5.5/M(HCl), where M(HCl) is the molar mass.
What are the mole fractions of hydrochloric acid HCl and water in a 20% aqueous HCl solution?
1 Answer. Stefan V. 0.1 and 0.9 , respectively.
How many moles are there in 73g HCl?
of molecules in 73 g HCl = 6.023 x1023 x 73/36.5(mol.
What is the mole fraction of HCl in a 12.4% by mass aqueous solution?
So, mass of HCl= 24.8g and mass of water = 100-24.8 = 75.2 g. Hence , mole fraction of HCl in the given solution is 0.139.
Does hydrochloric acid contain water?
Hydrochloric acid is the water-based, or aqueous, solution of hydrogen chloride gas. It is also the main component of gastric acid, an acid produced naturally in the human stomach to help digest food.
What is the molar mass of HCl?
What is mole fraction explain with example?
Mole fraction represents the number of molecules of a particular component in a mixture divided by the total number of moles in the given mixture. It’s a way of expressing the concentration of a solution. Mole Fraction formula.
How do you find the mole fraction of water in a solution?
The mole fraction formula for a solution with containing one or more solutes is: Mole fraction of each solute = Number of moles of that solute divided by the total number of moles of all solutes and the solvent.
How do you calculate molality and molarity in Class 11?
How to Calculate Molatity
- Find the Number of moles of Solute. if Mass is given ,then find the Molar mass, then calculate the Moles.
- Find the mass of the solvent in Kg. …
- Now that both moles and Solvent mass in kg is known, we can calculate the Molality using Molality Formula.
