Moles of HNO₃ = 63 g / (63 g/mol) = 1 mol
Weight of solvent = 750 g = 0.75 kg
Molality = Moles of solute / Weight of Solvent in kg
= 1 mol / (0.75 kg)
= 1.33 molal
Molality of solution is 1.33 molal
Weight of solvent = 750 g = 0.75 kg
Molality = Moles of solute / Weight of Solvent in kg
= 1 mol / (0.75 kg)
= 1.33 molal
Molality of solution is 1.33 molal
