Analysis of aluminum-zinc alloy

Mass of gelatin capsule 0.1284 g ambient temp. 22c
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,
ph2 ________________mm Hg
volume of displaced water
(density = 1.00 g/ml)_____________ml Pressure of dry _________atm
volume, v, of h2 = volume of displaced water __________ml_________liters

find the number of moles of h2 evolved nh2(v in liters, ph2 in atm, T in K, R= 0.0821 liter-atm/mole K) _____________________moles H2

find Nh2 the number of moles of H2 per gram of sample_________moles H2/g

find the % Al in the sample from the graph prepared _____________% Al

find the % Al in sample ____________________% Al

(please if you could help me filling these blanks)

It looks like this is a practical/experiment type questions that you should already have your the results. It would be easier if you enter your values for the temperatures and pressures and leave the mole calculations and % for help.
