Molality of Aqueous Solution of H2SO4
Given:
Mole fraction of water (H2O) = 0.6
Mole fraction of H2SO4 can be calculated as:
Mole fraction of H2SO4 = 1 - Mole fraction of water = 1 - 0.6 = 0.4
Calculating Molality:
- First, we need to find the moles of water and H2SO4 in the solution.
- Let's assume we have 1 mole of the solution for ease of calculation.
- Since the mole fraction of water is 0.6, the moles of water = 0.6 moles
- Similarly, moles of H2SO4 = 0.4 moles
- Next, we calculate the mass of water and H2SO4 using their respective molar masses.
- Finally, we use the formula for molality:
Molality (m) = moles of solute / mass of solvent (kg)
Assuming:
Molar mass of water (H2O) = 18 g/mol
Molar mass of H2SO4 = 98 g/mol
Mass of 1 mole of the solution = 18g (from water) + 98g (from H2SO4) = 116g
Thus, the mass of 1 mole of the solution = 0.116 kg
Substitute the values:
- For water: moles = 0.6, mass = 0.6 x 18g = 10.8g = 0.0108 kg
- For H2SO4: moles = 0.4, mass = 0.4 x 98g = 39.2g = 0.0392 kg
Now, calculate molality:
Molality = (0.6 / 0.0108) + (0.4 / 0.0392) = 55.56 + 10.2 = 65.76 m
