Stoichiometry

Using Dimensional Analysis Explanation:

Step 1: Define

0.132 g OF₂

Step 2: Identify Conversions

Avogadro's Number

Molar Mass of O - 16.00 g/mol

Molar Mass of F - 19.00 g/mol

Molar Mass of OF₂ - 16.00 + 2(19.00) = 54.00 g/mol

Step 3: Convert

Set up:                               Divide/Multiply:                                                                                              

Step 4: Check

Follow sig fig rules and round. We are given 3 sig figs.

1.47204 × 10²¹ molecules OF₂ ≈ 1.47 × 10²¹ molecules OF₂

So3 that’s what i think

The answer is b because c don't explain why the moths are on them and it isn't a because as we know only one species of moth does this
