Chemistry

A mixture of propan-1-ol and 2-methylpropan-2-ol of unknown contentmay also contain a small amount of water. To determine the% by massof its propan-1-ol and 2-methylpropan-2-ol content, the mixture wassubjected to the following experimental procedures:
A. 2 grams of the mixture is completely burned and 2.24 L of carbondioxide is produced under normal conditions.
B. B. Equal amount of the mixture (2 g) is transferred to a250 mL volumetric flask and diluted with distilled water to themark to give solution Y.
• To a conical flask containing 100 mL of 2 M H2SO4 solutionwas added accurately 10 mL of solution Y and 15 mL of 0.02 M KMnO4solution After stirring and gentle heating, the solution S wascolorless.
a) Write the chemical equations of the reactions with KMnO4carried out.
b) Calculate:
(i) the mol of KMnO4 added to the conical flask. (ii) mol ofpropan-1-ol in 10 mL of solution Y
iii) the percentage by mass (% w/w)of the propan-1-ol mixturecontent.
