ETHANE-1,2-DIAMINE (Flammable,causes burns,causes damage to organs,harmful.)(Complex ions.) (CHEMICAL CABINET 2)
graduated pipette to measure 0.33ml of ethyle.... to 500ml distilled water spectometer + green filter 7A + Staff Laptop
3 X burettes by chemical (6 in total), test tubes. teat pipettes, test tube holder, use a colorimeter + data logger instead of computer one
ethane-1,2-diamine 0.33ml to 500ml Distilled water make 0.01m
M1V1 = M2V2
14.8 X V1 =0.01 X 500ml
V1 = 0.01X 500 /14.8
V1 = 0.33ml
finding molarity of Ethylenediamine : FW(atomic weight) = 60.10 , d(density) = 0.899/1 ml
molarity = d/FW
molarity = 899(100ml) / 60.1
molarity = 14.95
because the solution is 99% the calculation is
molarity = 899/60.1x 99/100
m = 14.95 X 0.99
m= 14.80
