Generally absorbance is mathematically represented as
where is the molar absorptivity of FeSCN2 with a value
and is the equilibrium concentration of FeSCN2
So
substituting values
Answer:
Substance is Aluminium
Explanation:
We are given;
Mass; m = 13.5 grams
Volume; V = 5 cm³
Formula for density is;
density = m/V
Density = 13.5/5
Density = 2.7 g/cm³
From the table attached, we can see that the element with a corresponding density of 2.7 is Aluminium
