    For d, can I say that knowing the volume of aspirin solution used is not necessary because we only need to find the mass of aspirin reacted and this can be directly calculated by finding out the number of moles of NaOH used, because we are already given the relative molecular mass of aspirin.

    For f, is the answer to titrate a solution of aspirin with NaOH, and then evaporate to saturate the resulting solution, and then cool to crystallise the sodium salt, which is then obtained by filtration and dried between sheets of filter paper.
