(a) Interpretation Introduction To determine: Atomic mass of the given element X. Explanation Given: Mass of XI 3 is 0.5000 g . Mass of XCl 3 formed is 0.2360 g . The atomic mass of iodine is 127 g / mol . The atomic mass of chlorine is 35.5 g / mol . The atomic mass of the element X is supposed to be M. The molecular mass of XI 3 = X + 3 I = M+ ( 3 × 127 ) g / mol = ( 381+M ) g / mol The molecular mass of XCl 3 = X + 3 Cl = M+ ( 3 × 35.5 ) g / mol = ( 106 .5+M ) g / mol The stated reaction is, 2XI 3 + 3 Cl 2 → 2 XCl + 3 I 2 2 moles of XI 3 produce 2 moles of XCl 3 . Formula The number of moles of a substance can be calculated using the formula, Number of moles = Given mass of the substance Molecular mass of the substance Substitute the value of the given mass and the molecular mass in the above expression, For XI 3 , Number of moles = ( 0 (b) Interpretation Introduction To determine: The correct name of the given element X.
