A student analyzes a sample of \(\text{Br}_2\) prepared from isotopically enriched bromine. The only bromine isotopes present are \({}^{79}\text{Br}\) and \({}^{81}\text{Br}\). The molecular ions are singly charged, isotope incorporation at each atomic position is independent, and the detector response is the same for all isotopologues.

Molecular ion	\(m/z\)	Relative intensity
\(({}^{79}\text{Br})_2^{+\bullet}\)	\(158\)	\(36\)
\({}^{79}\text{Br}{}^{81}\text{Br}^{+\bullet}\)	\(160\)	\(x\)
\(({}^{81}\text{Br})_2^{+\bullet}\)	\(162\)	\(16\)

What is the expected relative intensity, \(x\), of the molecular-ion peak at \(m/z=160\)?
