(4) Samples of oxygen shall be taken and tested for purity at both the ends of the gas-pipes connecting the gas holder and the suction end of the compressor after the supply of oxygen to the gas-holder is cut off completely from the cells by means of a stop-valve. Testing of the gas for purity shall be reported thereafter every hour and records ...

4 g of NaOH in 250 cm3 of solution is equivalent to 4 x 1000/250 = 16 g in 1 litre. 16 g NaOH = 16/40 moles NaOH = 0.4 moles NaOH. Concentration of the solution = 0.4 mol l-1 (= 0.4 M) Question 9. A solution contains 4.9 g H2SO4 in 100 cm3 of solution. Calculate the concentration of the solution in moles per litre. Answer:

GAS DENSITIES AND MOLAR MASSES - AHISD
M = DV = (0.76 g/l)(22.4 l/mol) = 17.0 g/mol B. Density of a gas at non-STP. The ideal gas law can be used to find both density and molar mass when the conditions are non standard.

198 ( 30.5 mg Oxygen/L is based on a 2 % dilution of GGA (6 mL/300). It is important not to use multiple dilutions which use other than 6 mL). Seed is then added and the bottle is filled with dilution water. These bottles are incubated and BOD is determined similar to sample bottles. 3. The acceptable BOD5 value of the standard is 198 ( 30.5 mg/l.
