Question

how many boron atoms are there in 2 molecules of bf₃? hint: the symbol for boron is b.

Explanation:

Step1: Analyze the formula of \( BF_3 \)

In one molecule of \( BF_3 \), the subscript of \( B \) (boron) is 1, which means there is 1 boron atom per molecule of \( BF_3 \).

Step2: Calculate the number of boron atoms in 2 molecules

If 1 molecule of \( BF_3 \) has 1 boron atom, then for 2 molecules, we multiply the number of molecules by the number of boron atoms per molecule. So the number of boron atoms \( = 2\times1 = 2 \).

Answer:

2
