how many nitrogen atoms are there in 3 molecules of n₂h₄?

Answer

# Explanation: ## Step1: Analyze the number of nitrogen atoms in one molecule In one molecule of \(N_2H_4\), the subscript of \(N\) is \(2\), which means there are \(2\) nitrogen atoms in one molecule of \(N_2H_4\). ## Step2: Calculate the number of nitrogen atoms in 3 molecules If there are \(2\) nitrogen atoms in one molecule of \(N_2H_4\), then for \(3\) molecules, the number of nitrogen atoms is \(2\times3\). # Answer: \(6\)
