(આપેલ પરમણીય દળ $A=64 ; B=40 ; C=32 u$ )
Element | Mass percentage \(%\) | No. of moles |
No. of moles/ Smallest number |
Simplest whole number |
\(A\) | \(32 %\) | \( \frac{32}{64}=\frac{1}{2} \) | \(\frac{1}{2} \times 2\) | \(=1\) |
\(B\) | \(20 %\) | \( \frac{20}{40}=\frac{1}{2} \) | \(\frac{1}{2} \times 2\) | \(=1\) |
\(C\) | \(48 %\) | \( \frac{48}{32}=\frac{3}{2}\) | \(\frac{3}{2} \times 2\) | \(=3\) |
So, empirical formula\(*=A=1:B=1:C=3\)
\(\therefore\) The correct empirical formula of compound \(\mathrm{X}\) is \(\mathrm{ABC}_3\)
