### Assistant: Sodium (Na) has an atomic mass of 23 u, and Chlorine (Cl) has an atomic mass of 35.5 u. Thus, the molar mass of Sodium is 23 g/mol, and the molar mass of Chlorine is 35.5 g/mol. To find the number of moles of each element, we divide the mass of each element by its molar mass. So, we get 0.2 moles of Sodium and 0.16 moles of Chlorine. Since both Sodium and Chlorine have a valence of 1, the chemical formula for Compound X is NaCl. Calcium (Ca) has an atomic mass of 40 u, and Oxygen (O) has an atomic mass of 16 u. Thus, the molar mass of Calcium is 40 g/mol, and the molar mass of Oxygen is 16 g/mol. To find the number of moles of each element, we divide the mass of each element by its molar mass. So, we get 0.056 moles of Calcium and 0.11375 moles of Oxygen. Since Calcium has a valence of 2, and Oxygen has a valence of 2, we need to divide the number of moles of Oxygen by 2 to balance the valence of Calcium. Therefore, the chemical formula for Compound Y is CaO. , The answer is The chemical formula for Compound X is NaCl and the chemical formula for Compound Y is CaO.
