Determination Of The Relative Atomic Mass Of Lithium Assessed Practical 1 With the aim of determining the relative atomic mass of Lithium, two methods were used to measure this with greatest possible accuracy.> Reacting the Lithium with water and using the number of moles of H2 produced to calculate the number of moles of Lithium thus its relative atomic mass.> Titrating 0.1 molar HCl against the LiOH from method one to determine how many moles of HCl are needed to neutralise the LiOH, being able to measure the number of moles of LiOH thus calculating the relative atomic mass of the Lithium. Method One - Procedure 1. The required apparatus was set up as shown in the diagram below. 2. The Lithium was placed on a pan balance (having removed as much oil as possible), as this would need to be recorded for later calculations. 3. The measured mass of Lithium was placed in the...
