A coordination compound of Cu²⁺ can be described as Cu(NH₃)_xSO₄ and is known to contain 29.92% NH₃ by mass.The value of x is: A)2 B)3 C)4 D)6 E)none of these

Question

Quizplus · Accepted Answer

To find x, calculate the molar mass of Cu(NH3)xSO4 and set up the equation for the percentage of NH3. The molar mass of NH3 is 17 g/mol. Let M be the molar mass of Cu(NH3)xSO4. The equation is (17x/M) * 100 = 29.92. Solving for x gives x = 4.
