Question

how many hydrogen atoms are in 4h₂o?

Explanation:

Step1: Analyze the formula

In the formula \(H_2O\), the subscript \(2\) indicates the number of hydrogen atoms per molecule.

Step2: Consider the coefficient

The coefficient \(4\) in \(4H_2O\) means there are \(4\) molecules of \(H_2O\).

Step3: Calculate the total hydrogen atoms

Multiply the number of hydrogen atoms per molecule (\(2\)) by the number of molecules (\(4\)): \(2\times4 = 8\).

Answer:

\(8\)
