Answer 1):
a): Total volume of column= pi×r^2×l=3.14×(0.80^2)×(20.0) cm^3= 40.2 cm^3= 40.2 ml
b): Volume is occupied by the stationary phase plus the solvent inside the pores of the stationary phase= 18.2 ml + 40.2 ml= 58.4 ml
c): Volume (pores)= (40.2 ml× 60/100)=24.1 ml
Hence, volume range is 0-24.1 ml

3. A capillary column for use in gas chromatography is 30.0 m long and has an internal diameter of 0.320 mm. The inside wall of the capillary is coated with the stationary phase. a. The phase ratio (B) is the ratio of the mobile phase volume to the stationary phase volume: B = Vm/Vs. For a particular separation, the desired phase ratio is B = 200. What should the thickness of the stationary phase be to obtain this phase ratio?...
1-) Silica gel has a bulk density of about 0.3 g/cm3, so 15 g would occupy a volume of 45-50 cm3 (45-50 mL). This quantity is called the: 2-) You are carrying out a chromatographic separation on a 15 mg sample using 6.5 g of silica gel in your column. If you aim for a column height of 10 cm of silica gel, what is the inside diameter of the necessary chromatography column in units of cm? 3-) Consider the...
