Acetylsalicylic acid commonly known as Aspirin (C9H8O4) is used to treat fever, inflammation, and acts as a blood-thinning agent. A group of STEM students experimented on the synthesis of this compound using recrystallization technique. The following are the initial materials for the experiment: 5.00 g of pure salicylic acid (C7H6O3), 7.14 g of acetic anhydride (C4H6O3) and 8 drops concentrated sulfuric acid as catalyst. After successful synthesis, the group was able to collect 5.25 grams of Aspirin (C9H8O4) and acetic acid (C2H4O2). Atomic weights: C= 12 amu; H = 1 amu; O= 16 amu; density acetic anhydride = 1.08 g/mL How much of the excess reactant (in grams) will be left unconsumed after the reaction?

Alkanes and Cycloalkanes

Alkanes are saturated organic compounds which are made up of C and H atoms. Alkanes have the general formula of CnH2n+2. Alkane contains sp3 hybridized carbon atoms with four sigmas (σ) bonds & every hydrogen atom is connected with one of the carbon atoms. The size of the alkane could be determined by the number of carbon atoms located in it.
