Answer:
3 × 10²⁰ molecules C₉H₃O₄
Explanation:
Step 1: Define
Avagadro's Number: 6.02 × 10²³ atoms, molecules, formula units, etc.
Molar Mass C - 12.01 g/mol
Molar Mass H - 1.01 g/mol
Molar Mass O - 16.00 g/mol
Molar Mass C₉H₃O₄ - 175.12 g/mol
Step 2: Use Dimensional Analysis
= 3.43764 × 10²⁰ molecules C₉H₃O₄
Step 3: Simplify
We are give 1 sig fig.
3.43764 × 10²⁰ molecules C₉H₃O₄ ≈ 3 × 10²⁰ molecules C₉H₃O₄
A refracting telescope uses convex lenses to gather a large amount of light and focus it onto a small area while a reflecting telescope the mirror instead of an objective lens they are also similar because like the lenses in a refracting telescope the mirror in a reflecting telescope focuses a large amount of light onto a small area.
