Molality of 10%[w/w] aqueous H2SO4
Definition of Molality
Molality (m) is a unit of concentration that expresses the number of moles of solute per kilogram of solvent.
Formula for Molality
m = moles of solute / mass of solvent in kg
Calculation of Molality of 10%[w/w] aqueous H2SO4
10%[w/w] aqueous H2SO4 means that 10 grams of H2SO4 is present in 100 grams of solution. To calculate the molality of this solution, we need to know the molecular weight of H2SO4 which is 98 g/mol.
- The mass of H2SO4 in 100 g of solution = 10 g
- The mass of water in 100 g of solution = 90 g
- The number of moles of H2SO4 present in 10 g of H2SO4 = 10/98 = 0.102 moles
- The mass of water in kg = 90/1000 = 0.09 kg
- Molality of solution = 0.102 / 0.09 = 1.13 m
Conclusion
The molality of 10%[w/w] aqueous H2SO4 is 1.13 m.
