Cupric ammonium sulphate was found to contain
water of crystallization by mass. Upon
strongly heating, it gave cupric oxide corresponding
to of starting mass. Find the empirical
formula of cupric ammonium sulphate.
water of crystallization by mass. Upon
strongly heating, it gave cupric oxide corresponding
to of starting mass. Find the empirical
formula of cupric ammonium sulphate.
View answer and explanation
Correct option: A
Option A is correct because the empirical formula is determined by calculating the moles of each component and finding the simplest whole number ratio, which corresponds to CuSO₄⋅(NH₄)₂SO₄⋅6H₂O.
