1. A 0.1014 g sample of purified glucose was burned to produce 0.1486 grams of carbon dioxide and 0.09 g of water. Glucose contains only C,H,and O. Determine the empirical formula of glucose. If the molecular mass of glucose is 180, what is the molecular formula of glucose.
2. A granulated sample of aircraft alloy (Mg, Al, Cu) weighing 8.72 g was first treated with alkali to remove the aluminum and then with HCl(aq) to remove the magnesium, leaving a 0.9 g residue of Cu. If 6.067 g of aluminum hydroxide were recovered from the alkali treatment, what is the elemental mass percent composition of the alloy?
