    i'm not sure but i think; 1a) moles of Li = mass/molar mass= 0.120/6.9= 0.0173
    ratio of Li to H is 2:1 so, 0.0173/2= 0.0087 mol of Hydrogen
    volume of H= mol/molar volume= 0.0087 * 24 dm3= 0.2 dm3
    bi) 100cm3 capacity Volumetric flask

    Specific temp and pressure though so I ended up going with pv=nRt

    Still need help with the second page
