Determination of the relative atomic mass of Lithium In this investigation I am going to determine the relative atomic mass of lithium by two different methods. Method 1: I will measure the volume of hydrogen produced when a known mass of lithium reacts with water. Method 2: I will titrate the solution of lithium hydroxide produced. After I have done the two methods and established my results. I will compare the two methods and conclude on which method was more appropriate and reliable. Apparatus * Safety goggles * Protective gloves * 2 × 250 cm3 conical flasks * Delivery tube * 250 cm3 measuring cylinder * Clamp stand * 2 bosses * 2 clamps * Trough * 100cm3 measuring cylinders, burettes with clamps and stands or 25.00 cm3 pipettes and fillers * Pre-weighed lithium pieces of between 0.08g and 0.13g and stored in oil * 100cm3 distilled water * Forceps * Filter paper * 25.00cm3 pipette * Pipette filler * 50.00cm3 burette * Small funnel for filling burette * White...
