could you help me with problem 2 and 3 using the information and table giving ?

A chromatogram of a mixture of species (A, B, C and D) provided the following data from a column used typically in gas-liquid chromatography: Length of packing = 24.7 cm Flow rate = 0.313 mL/min Dead Volume (Vm) = 1.37 ml Volume of the stationary phase (Vs) = 0.164 mL Table 1 Retention Time (min) Width of peak base (min) Non retained 3.1 A 5.4 0.41 B 13.3 1.07 14.1 1.16 21.6 1.72 D (16 pts) Question 2: For species B and C in Table I calculate: a) the resolution b) the selectivity factor c) the length of the column necessary to give a resolution of 1.5 d) the time required to separate B and C with a resolution of 1.5 *Please pay careful attention to significant figure rules. (8 pts) Question 3: For species and Din Table I calculate: a) the resolution b) the length of the column necessary to give a resolution of 1.5 *Please pay careful attention to significant figure rules
