A student uses atom models to assemble models of \(\text{H}_2\text{O}\) molecules. The available numbers of atom models are shown in the table. Avogadro's constant is \(N_A=6.02\times10^{23}\ \text{mol}^{-1}\).

Atom model	Number available
\(\text{H}\)	\(6.02\times10^{23}\)
\(\text{O}\)	\(1.806\times10^{23}\)

What is the maximum amount of \(\text{H}_2\text{O}\) models that can be assembled, and which atom model is the limiting constituent?
