Answer: The retention factor describes the rate at which a compound migrates on a microscopic level.

The retention factor (Value) serves as a simple measurement of the relative binding of the compound of interest under the experimental conditions.

Retention factor values are used in identification purposes;

• Use to determine the affinity of the solute to the solvent

• Greater retention factor means greater affinity of solute to the solvent

Explanation:

The balanced chemical equation of the reaction is:

$C_3H_8(g)+ 5O_2 (g)->3CO_2(g)+4H_2O(g)$

From the balanced chemical equation,

1 mole of propane forms ------ 3 mol. of $CO_2$ gas.

The molar mass of propane is 44.1 g/mol.

One mole of any gas at STP occupies --- 22.4 L.

Hence, 44 g of propane forms (3x22.4 L=) 67.2 L of CO2 gas at STP.

Answer:

Thus, 67.2 L of CO2 is formed at STP.

Independent Variable: a variable that you can change in an experiment

Dependent Variable: something that changes as you change the independent variable

control variable: something that is not changed throughout the experiment

Molarity=(initial molarityxinitial volume)/final volume
M=(3.5x25.4)/166.7=0.533 M
