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
The components required for the electrolysis of molten NaCl are a source of electrical energy such as a battery and electrodes (anode and cathode). Electrolysis is the process of decomposing and electrolyte (either and aqueous solution or molten solution) by passing an electric current through it. During electrolysis the positive ion moves to the negatively charged electrode (cathode), while the negatively charged ions go to the anode.
81. There is 1 carbon, 2 chlorine and fluorine atoms in Freon 12. To draw them it forms a cross with C in the middle and Cl and F both on the opposite side.
Waves travel through matter, so I am 99.9% sure that is the answer.
