Wgts. of Slurry: Use the following for calculating the weights of slurry with varying percentages of water. W = 6237s / (100-a+sa) W = wgt in lbs of slurry per cu.ft. s = specific gravity of dry solids a = percent of water in slurry Conversion Equations: Energy: 1 cal = 4.184 J 1 ev = 1,602 x 10-19 J 1 L atm = 101.3 J Length: 1 A = 10-10 m 1 in = 2.54 cm 1 yd = 0.9144 m Volume: 1 L = 1 dm 1 qt = 0.9464 L Mass: 1 oz = 28.35 g 1 lb = 0.4536 kg Pressure: 1 atm = 760.0 mm Hg Periodic Table: (Legend at bottom) Sym No. Wgt H 1 1.01 1s He* 2 4.00 1s Li 3 6.94 2s Be 4 9.01 2s B 5 10.81 2p C 6 12.01 2p N 7 14.01 2p O 8 16.00 2p F 9 19.00 2p Ne* 10 20.18 2p Na 11 22.99 3s Mg 12 24.31 3s Al 13 26.98 3p Si 14 28.09 3p P 15 30.97 3p S 16 32.07 3p Cl 17 35.45 3p Ar* 18 39.95 3p K 19 39.10 4s Ca 20 40.08 4s Sc 21 44.96 3d Ti 22 47.88 3d V 23 50.94 3d Cr 24 52.00 3d Mn 25 54.94 3d Fe 26 55.85 3d Co 27 58.93 3d Ni 28 58.69 3d Cu 29 63.55 3d Zn 30 65.39 3d Ga 31 69.72 4p Ge 32 72.61 4p As 33 74.92 4p Se 34 78.96 4p Br 35 79.90 4p Kr* 36 83.82 4p Rb 37 85.47 5s Sr 38 87.62 5s Y 39 88.91 4d Zr 40 91.22 4d Nb 41 92.91 4d Mo 42 95.94 4d Tc 43 98.00 4d Ru 44 101.07 4d Rh 45 102.91 4d Pd 46 106.42 4d Ag 47 107.88 4d Cd 48 112.41 4d In 49 114.82 5p Sn 50 118.71 5p Sb 51 121.75 5p Te 52 127.60 5p I 53 126.90 5p Xe* 54 131.29 5p Cs 55 132.91 6s Ba 56 137.33 6s La 57 138.91 5d Ce 58 140.12 4f Pr 59 140.91 4f Nd 60 144.24 4f Pm 61 145.00 4f Sm 62 150.36 4f Eu 63 151.97 4f Gd 64 157.25 4f Tb 65 158.93 4f Dy 66 162.50 4f Ho 67 164.93 4f Er 68 167.26 4f Tm 69 168.93 4f Yb 70 173.04 4f Lu 71 174.97 4f Hf 72 178.49 5d Tn 73 180.95 5d W 74 183.85 5d Re 75 186.21 5d Os 76 190.20 5d Ir 77 192.22 5d Pt 78 195.08 5d Au 79 196.97 5d Hg 80 200.59 5d Tl 81 204.38 6p Pb 82 207.20 6p Bi 83 208.98 6p Po 84 209.-- 6p At 85 210.-- 6p Rn* 86 222.-- 6p Fr 87 223.-- 7s Ra 88 226.-- 7s Ac 89 227.-- 6d Th 90 232.03 5f Pa 91 231.-- 5f U 92 238.02 5f Np 93 237.-- 5f Pu 94 244.-- 5f Am 95 243.-- 5f Cm 96 247.-- 5f Bk 97 247.-- 5f Cf 98 251.-- 5f Es 99 251.-- 5f Fm 100 257.-- 5f Md 101 258.-- 5f No 102 259.-- 5f Lr 103 262.-- 5f Rf 104 261.-- 6d Ha 105 262.-- 6d Sg 106 263.-- 6d Ns 107 262.-- 6d Hs 108 265.-- 6d Mt 109 267.-- 6d 110 ---.-- 6d 111 ---.-- 6d 112 ---.-- 6d 113 ---.-- 6d Noble Gases* Lanthanides Actinides X Radioactive Page End
