Question

how many fluorine atoms are there in 2 molecules of hf? hint: the symbol for fluorine is f.

Explanation:

Step1: Analyze the formula of HF

In one molecule of HF (hydrogen fluoride), the chemical formula shows that there is 1 fluorine (F) atom per molecule of HF.

Step2: Calculate the number of F atoms in 2 molecules

To find the number of fluorine atoms in 2 molecules of HF, we multiply the number of molecules (2) by the number of F atoms per HF molecule (1). So the calculation is \( 2\times1 = 2 \).

Answer:

2
