Molar mass of sulfuric acid=98g/mole
Mass of sulfuric acid in 100 g of solution = 99g
Mass of water in 100 g of solution =1g = 0.001 kg
Number of moles of sulfuric acid in 100 g of solution = 99/98 =1.01 moles
Molality = number of moles of solute/ mass of solvent in kg
= 1.01/0.001
=1010 m
Mass of sulfuric acid in 100 g of solution = 99g
Mass of water in 100 g of solution =1g = 0.001 kg
Number of moles of sulfuric acid in 100 g of solution = 99/98 =1.01 moles
Molality = number of moles of solute/ mass of solvent in kg
= 1.01/0.001
=1010 m
