What is the molality of the salicylic acid in the solution (m)? The moles of the salicylic acid is 0.00727 mol and the given molar mass of it is 138.121. Given that 1.004g of salicylic acid was used.
Homework Answers
we need solvent mass to calculate molality
molality of slicylic acid solution = moles of salicyliic acid dissolved / ( solvent mass in kg)
we have data of moles of salicylic acid = 0.00727 mol
we need solvent ( H2O if used) mass in kgs
if solution mass is given we get solvent mass = solution mass - salicylic acid mass
( since solvent mass is not given , I just gave procedure to calculate molality)
