Question

how many atoms of hydrogen would there be total with a coefficient of 3 was placed with this molecule? rbh₂po₄ 5 6 7 21

Explanation:

Step1: Identify hydrogen atoms in one molecule

In \(RbH_2PO_4\), the sub - script of \(H\) is \(2\), so there are \(2\) hydrogen atoms in one molecule.

Step2: Multiply by the coefficient

The coefficient is \(3\). The total number of hydrogen atoms \(=3\times2\)

Answer:

\(6\)
