Answer:
A
Explanation:
Carbon dioxide in the air
Answer:
77460 g
Explanation:
To solve this problem first we<u> convert molecules into moles</u>, using <em>Avogadro's number</em>:
3.47x10²⁶ molecules ÷ 6.023x10²³ molecules/mol = 576.12 moles
Then we <u>convert 576.12 CuCl₂ moles into grams</u>, using its<em> molar mass</em>:
576.12 mol * 134.45 g/mol = 77460 g
So the answer is 77460 g, or 77.46 kg.
Stored in bonds of chemical compounds is the right answer
