Q1. Amylum, commonly known as starch is a white powder with variable molecular formula due to the different number of repeating sugar units based on the plant that it is obtained from. A sample of amylum in the form of spherical beads was subjected to series of analyses to determine physicochemical properties in the quality control unit of a factory. From the results each bead is found to have a 4.5 mL volume and 1.47 g/mL density. 4 of the beads were placed in a reaction chamber combusted, as a result, 43.1 g CO, and 14.7 g H2O were obtained. If the molecular weight of the amylum is 972.84 g/mol how many repeating units the starch molecule consist and what is the molecular formula of the starch? [Empirical Formula=CxHyOz, Repeating unit=n, Molecular Formula=( C×H,O2)*n= CnxHnyOnz]
