Question

Molarity of H2SO4 is 0.8 and its density is 1.06 g/mL.What will be its concentration of molality and mole fraction.

Answer 1

Explanation:

there is 0.8 mol of H2SO4 in 1L of solution

definition of molarity number of moles of solute present in one litre of solution molarity equals moles of solute by volume of solution

molarity=moles of solute/volume in litre

mass of solvent =981.6g

molality= 0.8149m =

molality=no of moles/mass of solvent in kg

mole fraction of solute

=moles of solute/moles of solute+moles solvent

mole fraction of solvent=moles of solvent/....

mole fraction of solute=0.0144

mole fraction of solvent=0.985
