Answer:
8.1%
Explanation:
<h3><u><em>mass of glucose/ total mass of solution x 100</em></u></h3>
So first 265mg into grams = 0.265 g
0.265 + 3 = 3.265
mass of glucose= 0.265
total mass of solution= 3.265
0.265/3.265 x 100 = 8.1% (rounded to 2 s.f)
We have to get the formula of the complex formed between Fe³⁺ and ethylenediamine.
The formula of the complex is: [Fe(<em>en</em>)₃]³⁺, where, <em>en</em> is abbreviation of ethylenediamine.
Ethylenediamine (<em>en</em>) is a bidentate ligand as it contains two donating sites (-NH₂ groups). Three ethylenediamine co-ordinate to central metal ion, Fe³⁺ and forms [Fe(<em>en</em>)₃]³⁺ with a co-ordination number of six.
