A) A flask contains initially 0.002 mol of Argon, occupying a volume of 50ml. Determine the volume occupied by the gas after having removed 0.040g

B) To verify Charles's law, you perform an experiment in which you expose a sealed syringe to different temperatures, initially containing 30.0 mL of air at a temperature of 20C. Calculate the volume occupied by air if you place the syringe in boiling water
