mass of capsule plus alloy sample 0.3432g ambient temp_________K
mass of alloy sample, m__________g barometric pressure 745 mm Hg
mass of empty beaker 144.5g Vapor pressure at
H2O at t_____________mm Hg
mass of beaker plus displaced
water 368.9
mass of displaced water ___________g Pressure of dry H2,
