Question

Can you explain the answer of this question below:... moreWhat will be the molality of the solution containing 18.25 g of HCl gas in 500 g of water?A:0.1 mB:1 MC:0.5 mD:1 m

Answer

Hii Nisha molar mass of HCl = 1+35.5= 36.5 Now moles of HCl = 18.25÷36.5=1/2 moles Therefore Molality = (1/2÷500 ) × 1000 = 1 m

Answer

Molality =number of moles of solute / mass of solvent In Kg. molality =mass of solute into 1000 / molecular mass of solute into mass of solvent. molecular mass of HCL is 36.50 given:- mass of solute and solvent are 18.25 gram and 500 gram respectively. put the value in above formula we get molality is 1m

Answer

Mass of HCl gas in 500 ml. = 18.25 g mass of HCl gas in 1000 ml = 18.25 X 2 = 36.50 g Molarity = Weight in one litre of solution ---------------------------------------------- = 36.5/36.5 Molecular weight of solute = 1 M ++++++±+++++++++++++++++++++++++++++++++++

Answer

1m ans-18.25/36.5*1000/500

Answer

Molality Calculation:

To calculate the molality of a solution, we need to find the moles of solute (HCl gas) and the mass of the solvent (water).

1. Calculate moles of HCl gas:
The molar mass of HCl is 36.46 g/mol. To find the moles, divide the given mass of HCl gas (18.25 g) by the molar mass:
Moles of HCl gas = 18.25 g / 36.46 g/mol
Moles of HCl gas = 0.500 mol

2. Calculate mass of water:
The given mass of water is 500 g.

Molality Formula:
Molality (m) = moles of solute / mass of solvent (in kg)

3. Convert the mass of water to kg:
Mass of water = 500 g = 0.500 kg

4. Calculate molality:
Molality (m) = 0.500 mol / 0.500 kg
Molality (m) = 1 m

Explanation:

The molality of the solution containing 18.25 g of HCl gas in 500 g of water is 1 m.

Molality is defined as the number of moles of solute per kilogram of solvent. In this case, we have 0.500 moles of HCl gas and 0.500 kg of water. Dividing the moles of HCl gas by the mass of water in kilograms gives us a molality of 1 m.

Summary:

- Moles of HCl gas = 0.500 mol
- Mass of water = 0.500 kg
- Molality (m) = 1 m

Answer

18.25*1000/(36.5*500)
