Chemistry Lab Help Titration

In lab I have.
200 mL of a standardised solution of NaOH (of appoximately 0.1 molar concetration)
labeled sample tube containing unknown acid or unknown base.
Indicator: phenolphthalein, Universal, methyl orange.

The aim of this laboratory is to determine the molar mass of an unknown acid by titration, and demonstrate the ability to choose laboratory equipment to allow you to perform a titration.

My questions are:
1. How will you confirm that your unknown sample is an acid.
2. How will you quickly, and accurately, weigh a sample of your unknown solid into appropiately, named, piece of laboratory equipment.
3. What solvent do you think would be most appropriate for the titration (the volume of solvent that should be used, and whether this volume should be accurately measured or approximately measured should be addressed when you discuss this point).
4. What steps should be taken to ensure that all of the unknown solid has dissolved.
5. What equipment, and other chemicals, might be used and how they should be used in the titration.
6. The measurement that must be recorded to enable you to determine the molar mass of your unknown sample and how you calculate error percentage.

Please explain in detail.
